Comment upon the harmonic regulation and selective reabsorption |
| Answer» Selective reabsorption\xa0is the process whereby certain molecules (e.g. ions, glucose and amino acids), after being filtered out of the capillaries along with nitrogenous waste products (i.e. urea) and water in the glomerulus, are\xa0reabsorbed\xa0from the filtrate as they pass through the nephron. Feedback mechanism\xa0refera to a syatem in which hormones are\xa0regulated\xa0according to demand. Example-when blood sugar level is high in body,message is sent to Feeback\xa0mechanism\xa0to\xa0regulate\xa0more Insulin and when required level is reached secretion becomes normal. | |

What is the difference between NAD+ and NADP+ |
| Answer» Nicotinamide adenine dinucleotide phosphate, or\xa0NADP+, is a similar molecule\xa0with a\xa0similar function, differing from\xa0NAD+\xa0in that it contains an additional phosphate group. The oxidized form is\xa0NADP+, while the reduced form is NADPH.\xa0The\xa0function of NAD+\xa0that is\xa0similar to that of NADP+\xa0is that each\xa0NAD+\xa0accepts a pair of high-energy electrons. Describe glycolsis in terms of energy input, energy output, and net gain of ATP. In glycolysis, glucose is converted to molecules of pyruvic acid. ...\xa0NAD\xa0becomes NADH.\xa0The\xa0main role of NAD+\xa0in metabolism is the transfer of electrons from one molecule to another. Reactions of this type are catalyzed by a\xa0large\xa0group of enzymes called oxidoreductases. | |

Describe the process of mature nodule? |
| Answer» Root\xa0nodules\xa0are found on the roots of\xa0plants, primarily legumes, that form a symbiosis with nitrogen-fixing bacteria. Under nitrogen-limiting conditions, capable\xa0plants\xa0form a symbiotic relationship with a host-specific strain of bacteria known as rhizobia. Nodules\xa0are\xa0formed\xa0as a result of infection of the roots by soil bacteria. ... The complex process by which plant roots are infected by rhizobia is known as infection. The complex process in which\xa0nodules\xa0are\xa0formed\xa0is known as nodulation. | |

How many amount of ATP is produce in glycolyis ,Krebs cycle and ETS? |
| Answer» Glycolysis produces\xa02 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.\xa0Cellular respiration has a potential to\xa0produce\xa0between\xa036\xa0and 38 moles of\xa0ATP\xa0per mole of glucose (C6H12O6). ... Each NADH [from glycolysis]\xa0produces\xa0a net 1.5\xa0ATP\xa0(instead of usual 2.5) due to NADH transport over the mitochondrial membrane.\xa0Glycolysis\xa0has mainly two parts: First part converts glucose to Fructose, consuming 2\xa0ATP. Second part converts the fructose into pyruvate,\xa0producing\xa02\xa0ATP\xa0(the process occurs twice, so it\xa0producing\xa0a total of\xa04 ATP) | |

Apoplast and symplast mechanism |
| Answer» Apoplast is the space outside the plasma membrane consisting of intercellular spaces where the material diffuses freely. It does not involve protoplasm in the plant tissues but involves the non-living parts of the plant such as cell wall and intercellular spaces.The pathways of ion and water created by symplast are known as the symplastic pathway. This pathway offers resistance to the flow of water since the selective plasma membrane of the root cells handles the intake of ion and water. Moreover, symplasty is affected by metabolic states of the root. The symplastic route occurs beyond the endodermis in plants with secondary growth. | |

Alimentary canal part and part function |
| Answer» he main organs of the alimentary canal are:\tThe Mouth and Oral cavity.\tEsophagus.: It is a muscular tube through which small bolus of food passes from the mouth to the stomach. It is sharply bent at the point at which it meets the stomach. This prevents the backward movement of food from the stomach into it. Food in the digestive tract moves by an involuntary movement of alternate contraction and relaxation of muscles called peristalsis.\tStomach:\tIt is a muscular bag which has three parts- cardiac part, fundus, and body.\t\tCardiac part– It is so called because it is present close to the heart. The opening of the esophagus to the stomach is regulated by the cardiac sphincter.\tFundus– It is dome-shaped and is usually filled with air.\tBody– This is the main part of the stomach. The opening of the stomach into the small intestine is regulated by the pyloric sphincter.\tLargeintestine.The small intestine leads into the large intestine which has three parts- Caecum, Colon, and Rectum.\tCaecum– It is a small sac-like structure at the point where the small intestine meets the large intestine.\tColon– It is divided into four regions- transverse colon, sigmoid colon ascending colon\xa0and descending colon.\tRectum– It opens into the ****.\tSmall intestine.:It is the longest part of the alimentary canal and comprises three parts- Duodenum, Jejunum, and Ileum.\tDuodenum– It is C- shaped and receives the hepatopancreatic duct formed by the union of bile and pancreatic duct.\tJejunum– Middle part of small intestine with thick walls and more vasculature.\tIleum– The lower part of the small intestine with thin walls and less vasculature.\tMouthThe mouth is the opening through which the intake of food occurs.\tOral cavityThe oral cavity has three parts –the palate, tongue, and teeth.Palate -It forms the roof of the oral cavity. The anterior part is called hard palate and the posterior part is called soft palate.Tongue -Tongue is a muscular and glandular structure attached to the base of the oral cavity. On the upper surface, it has a V-shaped furrow called sulcus terminalis. It divides the tongue into the anterior oral part and posterior pharyngeal part. Its upper surface also consists of tiny projections called lingual papillae. Lingual papillae are of three kinds in humans-(i)Vallate or circumvallate papillae -have gustatory receptors to sense taste(ii) Filiform papillae- smallest and contain touch receptors.(iii) Fungi-form papillae- Rounded and mostly present at the tip of the tongue.\tTeethHumans are diphyodont i.e. they have two sets of teeth- milk or deciduous and permanent teeth. Here is the list of different types of teeth in humans with their functions.\xa0 | |

Alimantary canal all part and function |
| Answer» The human digestive system consists of the alimentary canal and its associated glands. Food is taken into the body through the mouth. Digestion in human beings starts in the mouth. The mouth contains teeth, tongue and salivary glands. The teeth cut the food into small pieces, chew and grind it. The tongue mixes the food with saliva. The salivary glands secrete a watery liquid called saliva.The slightly digested food goes into the food pipe or oesophagus by peristalsis. No digestion of food takes place in the oesophagus. The slightly digested food reaches the stomach through oesophagus for further digestion where it is broken down into smaller pieces. The inner lining of the stomach secretes gastric juice which includes mucus, hydrochloric acid and digestive juices. Mucus protects the lining of the stomach from hydrochloric acid. Hydrochloric acid makes the medium in the stomach acidic to facilitate the digestion of proteins. The digestive juices break down the protein into simpler substances. Then the partially digested food goes into the small intestine.The small intestine is a very long and narrow tube where complete digestion of food takes place. It receives secretions of liver, pancreas and its own walls. Liver secretes liquid called bile which helps in the digestion of fats and converts them into small droplets. Pancreas secretes pancreatic juice which breaks down fats into fatty acids and glycerol. Pancreatic juice also breaks down carbohydrates and proteins into simpler forms. The intestinal juice secreted by the walls of small intestine breaks down the carbohydrates into glucose, proteins into amino acids. Thus, the food gets completely digested in small intestine.Absorption: The digested food material passes into the blood vessels in the walls of small intestine. This process is called absorption. The inner walls of small intestine have millions of tiny, finger-like outgrowths called villi which increase the surface area for rapid absorption of digested food. Each villus has a network of blood vessels which absorbs the digested food materials into the blood flowing through them.Assimilation: The blood carries the absorbed food materials to the cells in all the parts of the body where it is used for growth, energy and repair. This is called assimilation. Glucose breaks down utilizing oxygen to form carbon dioxide and water, and releases energy. The undigested and unabsorbed food passes from the small intestine into large intestine. Most of the water is absorbed from the undigested food materials in the large intestine. Egestion: The undigested food is temporarily stored in the last part of the large intestine called rectum and finally the semi-solid waste is passed out from the body through **** in the form of faeces. This is called egestion.Teeth: Teeth break down the food into smaller pieces. There are four types of teeth in our mouth. They are:\tIncisors: These are chisel shaped teeth at the front of the mouth and used for biting and cutting the food.\tCanines: These are large and pointed teeth just behind the incisors and are used for piercing and tearing the food. \tPremolars: These are large teeth just behind the canines on each side and are used for chewing and grinding the food.\tMolars: These are very large teeth present just behind the premolars and help for chewing and grinding the food. | |
