Explain the auto regulation mechanism of GFR |
| Answer» There is an auto regulatory mechanism present in the kidney to regulate the glomerular filtration rate. This mechanism is carried out by juxta glomerular apparatus (JGA) which is a special sensitive region formed by cellular modification of the distal convoluted tubule and the different arteriole at the location of their contact. A fall in the GFR will activate the JG cells to release renin which converts the angiotensinogen in blood to angiotensin I and later into angiotensin II. The angiotensin II is a powerful vaso constrictor which increases the glomerular blood pressure and there by increase the GFR. The Angiotensin II also activates the adrenal cortex to release aldosteron which causes the reabsorption of Na+ and water from the distal parts of the tubule. This also results in the increase in blood pressure and GFR. | |

How the impulse pass through the axon membrane in side or outside or through node of Ranvier ?? |
| Answer» A\xa0nerve\xa0cell is like a receiver, transmitter and\xa0transmission\xa0line with the task of passing a signal\xa0along\xa0from\xa0its\xa0dendrites to the\xa0axon\xa0terminal bundle. ... This enhanced signal\xa0transmission\xa0is called saltatory conduction.\xa0Myelin insulates the\xa0axon\xa0to prevent leakage of the current as it travels down the\xa0axon.\xa0Nodes of Ranvier\xa0are gaps in the myelin\xa0along the axons; they contain sodium and potassium ion channels, allowing the action potential to travel quickly down the\xa0axon by\xa0jumping\xa0from\xa0one\xa0node\xa0to the next. | |

How does butter in your food get digested and absorbed i the body |
| Answer» Digestion of fats:Butter is a fat product and gets\xa0digested in the small intestine. The bile juice secreted by the liver contains bile salts that break down large fat globules into smaller globules, so as to increase their surface area for the action of lipase. This process is referred to as emulsification of fats.After this,\xa0the pancreatic lipase present in the pancreatic juice and the intestinal lipase present in the intestinal juice hydrolyse the fat molecules into triglycerides, diglycerides, monoglycerides, and ultimately into glycerol and fatty acids.FatsTriglycerides + DiglyceridesDiglycerides and monoglyceridesFatty acids + GlycerolAbsorption of fats:Fat absorption is an active process. During fat digestion, fats are hydrolysed into fatty acids and glycerol. However, since these are water insoluble, they cannot be directly absorbed by the blood. Hence, they are first incorporated into small droplets called micelles and then transported into the villi of the intestinal mucosa.They are then reformed into small microscopic particles called chylomicrons, which are small, protein-coated fat globules. These chylomicrons are transported to the lymph vessels in the villi. From the lymph vessels, the absorbed food is finally released into the blood stream and from the blood stream, to each and every cell of the body. | |

What is mean by epithelial tissue |
Answer» \xa0\t\tTissue has a free surface, which faces either a body fluid or the outside environment and thus provides a covering or a lining for some part of the body. The cells are compactly packed with little intercellular matrix.\t\t\tThere are two types of epithelial tissues namely simple epithelium and compound epithelium, Simple epithelium is composed of a single layer of cells and functions as a lining for body cavities, ducts, and tubes. The compound epithelium consists of two or more cell layers and has protective function as it does in our skin.\t\t\tOn the basis of structural modification of the cells, simple epithelium is further divided into three types. These are\t(i) Squamous, (ii) Cuboidal, (iii) Columnar.\xa0 \xa0\t\tThe squamous epithelium is made of a single thin layer of flattened cells with irregular boundaries. They are found in the walls of blood vessels and air sacs of lungs and are involved in a functions like forming a diffusion boundary.\t\t\tThe cuboidal epithelium is composed of a single layer of cube-like cells. This is commonly found in ducts of glands and tubular parts of nephrons in kidneys and its main functions are secretion and absorption. The epithelium of proximal convoluted tubule (PCT) of nephron in the kidney has microvilli.\t\t\tThe columnar epithelium is composed of a single layer of tall and slender cells. Their nuclei are located at the base. Free surface may have microvilli. They are found in the lining of stomach and intestine and help in secretion and absorption. If the columnar or cuboidal cells bear cilia on their free surface they are called ciliated epithelium. Their function is to move particles or mucus in a specific direction over the epithelium. They are mainly present in the inner surface of hollow organs like bronchioles and fallopian tubes.\t\t\tSome of the columnar or cuboidal cells get specialised for secretion and are called glandular\' epithelium. They are mainly of two types: unicellular, consisting of isolated glandular cells (goblet cells of the alimentary canal), and multicellular, consisting of cluster of cells (salivary gland).\t\t\tCompound epithelium is made of more than one layer (multi-layered) of cells and thus has a limited role in secretion and absorption. Their main function is to provide protection against chemical and mechanical stresses. They cover the dry surface of the skin, the moist surface of buccal cavity, pharynx, inner lining of ducts of salivary glands and of pancreatic ducts.\t\xa0 It is a type of tissue which basically provide framework for body as found in exposed places in body. eg skinIt is of two types.

Why does the anaerobic respiration produces less energy than aerobic respiration? |
|
Answer» Because less no of ATP is produced during anaerobic respiration only two ATP molecules. While in aerobic respiration more no of ATP is generated 36-38 ATP molecules are formed Anaerobic respiration generates less energy because only glycolysis occurs which forms 2ATP molecules.However in aerobic repiration there is krebs cycle taking place\xa0which is responsible for making around 30 ATP molecules. In total, aerobic respiration generates 36-38 ATP molecules. |

What are deficieny symptoms micronutrients for plants? |
|
Answer» Necrosis, chlorosis, inhibition of cell division, delay flowering, stunted plant growth, premature form of leaves and buds The absence of any element necessary for the nourishment of that particular plant will lead to the morphological changes. And this change is an indication of a deficiency.Of course, if the deficient element is provided to the plant in good time, the symptoms of deficiency disappear. However, if the process is delayed, eventually the plant will die. |

What is jacob syndrome |
| Answer» XYY\xa0syndrome\xa0is a genetic condition that occurs when a male has an extra copy of the Y chromosome in each of their cells (XYY). Sometimes, this mutation is only present in some cells. Males with XYY\xa0syndrome\xa0have 47 chromosomes because of the extra Y chromosome.\xa0Most cases of 47,XYY\xa0syndrome\xa0are not\xa0inherited. The chromosomal change usually occurs as a random event during the formation of sperm cells. An error in cell division called nondisjunction can result in sperm cells with an extra copy of the Y\xa0chromosome.Boys with XYY syndrome may have some or all of these physical symptoms to some degree:\ttaller than average height.\tlow muscle tone, or muscle weakness (called hypotonia)\tvery curved pinky finger (called clinodactyly)\twidely spaced eyes (called hypertelorism)\tcystic acne during adolescence. | |

What are difference between mitosis and meiosis |
| Answer» \tTypesMitosisMeiosis\xa0Interphase\xa0Each chromosome replicates. The result is two genetically identical sister chromatids.\xa0Interphase – Chromosomes not yet visible but DNA has been duplicated or replicated.\xa0Prophase\xa0Prophase I – crossing-over recombination – Homologous chromosomes (each consists of two sister chromatids) appear together as pairs. Tetrad is the structure that is formed. Segments of chromosomes are exchanged between non-sister chromatids at crossover points known as chiasmata (= crossing-over).\xa0Prophase –Each of the duplicated chromosomes appears as two identical or equal sister chromatids, The mitotic spindle begins to form. Chromosomes condense and thicken.\xa0Metaphase\xa0Metaphase I Chromosomes adjust on the metaphase plate. Chromosomes are still intact and arranged as pairs of homologues.\xa0Metaphase -The chromosomes assemble at the equator at the metaphase plate.\xa0Anaphase\xa0Anaphase I Sister chromatids stay intact. But homologous chromosomes drift to the opposite or reverse poles.\xa0Anaphase – The spindle fibres begin to contract. This starts to pull the sister chromatids apart. At the end of anaphase, a complete set of daughter chromosomes is found each pole.\xa0Mode of Reproduction\xa0Asexual Reproduction.\xa0Sexual\xa0Reproduction.\t | |

Sliding filament theory |
| Answer» \tSliding filament theory explains the mechanism of muscle contraction, which states that contraction of a muscle fibre takes place by the sliding of the thin filaments over the thick filaments.\tThe junction between a motor neuron and the sarcolemma of the muscle fibre is called the neuromuscular junction or motor-end plate.\tA neural signal, released by central nervous system, when reaches the junction releases a neurotransmitter (Acetyl choline) which generates an action potential in the sarcolemma, which spreads through the muscle fibre and causes the release of calcium ions into the sarcoplasm. | |

Defination of water potential |
| Answer» \tWater potential is the difference between free energy of water molecules in a pure solvent and free energy of water molecules in a solution.\tSolute potential (Ψs) and pressure potential (Ψp) are the two main components that determine water potential.\tThe greater the concentration of water in a system, the greater is its kinetic energy or ‘water potential’.\tWater potential is denoted by the Greek symbol Psi or Ψ and is expressed in pressure units such as pascals (Pa).\tThe water potential of pure water at standard temperatures is taken to be zero.\tAll solutions have a lower water potential than pure water; the magnitude of this lowering due to dissolution of a solute is called solute potential.\tFor a solution at atmospheric pressure (water potential) Ψw = (solute potential) Ψs.\tThe pressure exerted by the protoplasts due to entry of water against the rigid walls is called pressure potential (Ψp).\tWhen water enters a plant cell due to diffusion causing a pressure built up against the cell wall, it makes the cell turgid, which increases the pressure potential.\tWater potential of a cell is affected by both solute and pressure potential: Ψw = Ψs + Ψp | |

what is the central molecule of chlorophyll molecule and how does it help in transport? |
| Answer» Chlorophyll, any member of the most important class of pigments involved in photosynthesis, the process by which light energy is converted to chemical energy through the synthesis of organic compounds.\xa0Chlorophyll\xa0is found in virtually all photosynthetic organisms, including green plants, cyanobacteria, and algae.\xa0Chlorophyll is\xa0the\xa0molecule\xa0that absorbs sunlight and uses its energy to synthesise carbohydrates from CO2\xa0and water. This process\xa0is\xa0known as photosynthesis and\xa0is\xa0the basis for sustaining the life processes of all plants.\xa0In addition to giving plants their green color, chlorophyll is vital for\xa0photosynthesis\xa0as it helps to channel the\xa0energy\xa0of sunlight into chemical\xa0energy. With\xa0photosynthesis, chlorophyll absorbs\xa0energy\xa0and then transforms water and carbon dioxide into oxygen and carbohydrates. | |

Notes of photo respiration topic |
| Answer» \tThe first step of the Calvin pathway is the first CO2 fixation step.\tRespiration is the reaction where RuBP combines with CO2 to form 2 molecules of 3PGA, that is catalysed by RuBisCO.RuBP + CO2\xa0-> 2 X 3PGA\tRuBisCO has a much greater affinity for CO2 than for O2.\tIn C3 plants, some O2 do bind to RuBisCO, and hence CO2 fixation is decreased.\tThe RuBP instead of being converted to 2 molecules of PGA binds with O2 to form one molecule and phosphoglycolate in a pathway called photorespiration.\tIn the photorespiratory pathway, there is neither synthesis of sugars, nor of ATP. | |
