What is citric cycle? |
| Answer» The\xa0eight\xa0steps of the citric acid cycle are a series of redox, dehydration, hydration, and decarboxylation reactions. Each turn of the cycle forms one GTP or\xa0ATP\xa0as well as three NADH molecules and one FADH2 molecule, which will be used in further steps of cellular respiration to produce\xa0ATP\xa0for the cell.\xa0The\xa0citric acid cycle, also known as the\xa0Krebs cycle\xa0or the tricarboxylic\xa0acid cycle, is at the center of cellular metabolism, playing a starring role in both the process of energy production and biosynthesis. It finishes the sugar-breaking job started in glycolysis and fuels the production of ATP in the process.\xa0In eukaryotes, the\xa0citric acid cycle\xa0takes place in the matrix of the mitochondria, just like the conversion of pyruvate to acetyl CoAstart text, C, o, A, end text. In prokaryotes, these steps both\xa0take place\xa0in the cytoplasm. | |

Step of kerb cycle |
| Answer» Step 1Acetyl Co-A combines with a four-carbon compound, oxaloacetate, and releases the CoA group resulting in a six-carbon molecule called citrate.Step 2In the second step, citrate gets converted to isocitrate, an isomer of citrate. This is a two-step process. Citrate first loses a water molecule and then gains one to form isocitrate.Step 3The third step involves oxidation of isocitrate. A molecule of carbon dioxide is released leaving behind a five-carbon molecule, ɑ-ketoglutarate. NAD+ gets reduced to NADH. The entire process is catalyzed by the enzyme isocitrate dehydrogenase.Step 4Here, ɑ-ketoglutarate is oxidized reducing NAD+ to NADH and releasing a molecule of carbon dioxide.CoA is picked up by the remaining four-carbon molecules forming an unstable compound succinyl CoA. ɑ-ketoglutarate dehydrogenase catalyzes the entire process.Step 5CoA from succinyl CoA is replaced with a phosphate group. It is then transferred to ADP to make ATP. Succinate, a four-carbon molecule is produced in this step.Step 6Succinate is oxidized to fumarate. Two hydrogen atoms are transferred to FAD to produce FADH2. FADH2 transfers its electrons directly to the electron transport chain since the enzyme carrying out the reaction is embedded in the inner membrane of mitochondria.Step 7A water molecule is added to fumarate which is then converted to malate.Step 8The oxidation of malate regenerates oxaloacetate, a four-carbon compound, and another molecule of NAD+ is reduced to NADH in this step. | |

What is \'hay flick limit \'? |
| Answer» The Hayflick limit or Hayflick phenomenon is the number of times a normal human cell population will divide before cell division stops.\xa0 | |
| 6135. |
Describe the phase of mitotic division in prokaryotes |
| Answer» Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other cell structures. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles. All of these cell parts must be duplicated and then separated when the cell divides. A chromosome is a coiled structure made of DNA and protein, and will be the focus of a subsequent concept. | |

What are advantages and disadvantages of sexual reproduction and asexual reproduction |
| Answer» The advantages of Asexual Reproduction are:\tIt is a faster means of reproduction \tLess energy required for reproduction\tNumber of progeny produced is moreThe disadvantage of Asexual Reproduction is:\tThe daughter offspring look exactly and have the same genetic material as the parent\tlack of genetic variation. So as a result the population may go extinct with dramatic changes in environment.\xa0The advantage of Sexual Reproduction is:\tIt allows for genetic variation due to the involvement of two parentsThe advantages of Sexual Reproduction are: | |

Feautres of euglonoid |
| Answer» Some characteristic features of Euglenoids are as follows.• Euglenoids (such as Euglena) are unicellular protists commonly found in fresh water.• Instead of cell wall, a protein-rich cell membrane known as pellicle is present.• They bear two flagella on the anterior end of the body.• A small light sensitive eye spot is present.• They contain photosynthetic pigments such as chlorophyll and can thus prepare their own food. However, in absence of light, they behave similar to heterotrophs by capturing other small aquatic organisms.• They have both plant and animal-like features, which makes them difficult to classify and hence they are called as connecting link between plants and animals. | |

Structure of theorosic cage |
| Answer» The\xa0thoracic cage\xa0protects the heart and lungs. It is composed of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12\xa0thoracic\xa0vertebrae. The sternum consists of the manubrium, body, and xiphoid process | |

What is partial pressure |
| Answer» Partial pressure is\xa0the pressure that a gas in a mixture of gases would exert if it occupied the same volume as the mixture at the same temperature. | |

What are aminoacids?discus their types and functions |
| Answer» Amino acids are organic molecules that, when linked together with other amino acids, form a protein. Amino acids are essential to life because the proteins they form are involved in virtually all cell functions.\xa0Amino acids, often referred to as the building blocks of proteins, are compounds that play many critical roles in your body. They\'re needed for vital processes like the building of proteins and synthesis of hormones and neurotransmitters. | |

What is the difference between piokilothermous and homoiothermous |
| Answer» Poikilothermic animals are usually defined as those living species that are able to adapt to the changing environmental conditions, by undergoing variations in the internal body temperature. They are also considered to be cold-blooded animals.For example, reptiles and fishes.On the other hand, homeothermic animals are referred to as those living species that able to regulate their body temperature by maintaining constant internal body temperature and are commonly considered as warm-blooded animals.For example, birds and mammals. | |

Define systematic? |
|
Answer» The word "systematics" is derived from the Latin word \'systema\' which means systematic arrangement of organisms. Linnaeus coined the term systematics in 1751. Systematic is the branch of biology that deals with classification of organisms based on their evolutionary relationship. Systematic errors are those errors which arises due to the repetition of same values due to fault im instruments. These errors tends to be in one direction either positive or negative.Causes of systematic errors are:i) Instrumental errors : These errors occurs due to imperfect design or callibration of measuring instruments.ii) Imperfect experimental technique or procedureiii) Personal errors: These errors occurs due to the lack of proper setting of apparatus or observer\'s carelessness while taking observations. |
