In which case a cofactor becomes a prosthetic group. |
| Answer» A cofactor that firmly attaches to the apoenzyme is called prosthetic group.Prosthetic groups are organic compounds and are distinguished from other cofactors in that they are tightly bound to the apoenzyme. For example, in peroxidase and catalase, which catalyze the breakdown of hydrogen peroxide to water and oxygen, haem is the prosthetic group and it is a part of the active site of the enzyme. Cofactor may be organic or inorganic (metal ions). | |

Digeshan mean |
| Answer» Digestion: The macromolecules in food cannot be utilised by our body in their original form. They need to be broken down and converted into simple substances so that they could be absorbed. The process of converting complex food into absorbable forms is called digestion. Various mechanical and biochemical methods are involved in digestion of food. | |

What is mean by human digeshan |
| Answer» Digestion is the process by which food is broken down into simple absorbable substances. Digestion of food takes place in the digestive system. Digestive system is made up of alimentary canal and associated glands.Parts of alimentary canal:The mouth, oesophagus, stomach, small intestine and large intestine form the alimentary canal. It is also known as the digestive tract.Mouth is guarded by upper lip and lower lip. The process of taking in food through mouth is called as ingestion.Buccal cavity is the inner region of the mouth. It encloses teeth and tongue.Teeth are of different types namely, incisors, canines, premolars and molars.Incisors are used for biting food.Canines are sharp and pointed and are used to pierce or tear food.Premolars and molars are the principal grinders helping to chew and grind the food.Tongue is a muscular organ attached to the floor of the buccal cavity at the back. It helps in mixing of food with saliva and swallowing it. It also helps in tasting different types of food with the help of taste buds present on it. The buccal cavity leads into pharynx.Pharynx is at the back of buccal cavity. The pharynx is the common channel for food and air. When you swallow food, a flap-like valve called the epiglottis closes the windpipe. It prevents the entry of food particles into respiratory tract.Oesophagus also called as food pipe helps in conveying the food from buccal cavity to stomach. The oesophagus is also known as the gullet. It is about 25 centimetres long. Food inside the oesophagus reaches the stomach by peristalsis movements.Stomach is the widest part of the alimentary canal. It is a J-shaped muscular organ with stomach occurs with the help of digestive juice. Digestive juice comprises of hydrochloric acid, mucous and some enzymes.Small intestine is made up of three regions namely duodenum, jejunum and ileum. Partially digested food called the chyme from the stomach is received by the duodenum. Duodenum also receives bile form the liver, enzymes from pancreas and secretes some enzymes on its own. All these substances bring about digestion of food in the intestine. The inner walls of the small intestine have millions of small finger like projections called the villi. Villi increase the surface area for digestion as well as absorption of digested food by eight times.Large intestine comprises of colon and rectum. Undigested food is sent into large intestine. Water from the food is reabsorbed to a great extent in the large intestine. Undigested waste is stored in the rectum for defecation.**** is the opening of the alimentary canal to the exterior. This helps in the elimination of faeces by the process of egestion.Associated glands: These glands include salivary glands, gastric glands, intestinal glands, liver and pancreas.Salivary glands are present inside the buccal cavity. They secrete saliva. This saliva plays an important role in breaking down complex components like starch into simple sugars.Gastric glands present inside the stomach secrete gastric juice which helps in the digestion of food.Intestinal glands secrete various enzymes which aid in the process of digestion of food.Liver is the largest gland in our body. The liver secretes a yellowish green watery fluid called bile. It is temporarily stored in a sac called the gall bladder. Bile plays an important role in the digestion of fats. Bile is sent into duodenum through a narrow tube-like structure called the bile duct. Bile breaks the larger fat molecules into tiny droplets, thereby increasing their surface area, which helps in the digestion of fats easily.Pancreas is the mixed gland. It acts as a both endocrine and exocrine gland. The pancreas secretes the pancreatic juice that helps to digest carbohydrates, proteins and fats. The pancreatic juice converts carbohydrates into simple sugars and glucose, proteins into amino acids, and the lipids into fatty acids and glycerol. | |

Explain the mechanism of FSH action |
| Answer» Follicle stimulating hormone produces its effect by binding to its specific receptors present on the ovarian cell membrane.Binding of FSH hormone to its receptor leads to the formation of hormone receptor complex. The formation of this complex leads to biochemical changes in the ovarian follicle, present in the ovary. The ovarian follicles mature and release a mature ovum in the fallopian tube for fertilization.POSTED BY EXPERT!! | |

What are the three major threat categories of species?describe with exampel. |
| Answer» The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened:\tVulnerable species\tEndangered species\tCritically endangered speciesLess-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data (data deficient) also are not considered "threatened" by the IUCN. | |

Is solute potential and water potential are same? |
| Answer» Solute potential\xa0(Ψs) decreases with increasing\xa0solute\xa0concentration; a decrease in Ψs causes a decrease in the total\xa0water potential. The internal\xa0water potential\xa0of a plant cell is more negative than pure\xa0water; this causes\xa0water\xa0to move from the soil into plant roots via osmosis.\xa0Osmotic potential\xa0is directly proportional to the\xa0solute\xa0concentration. If the\xa0solute\xa0concentration of a solution increases, the\xa0potential\xa0for the\xa0water\xa0in that solution to undergo osmosis decreases. ... If no physical pressure is applied to a solution, then the\xa0solute potential\xa0is\xa0equal\xa0to the\xa0water potential. | |

What is the uses of yeast , mushrooms and mould |
| Answer» Uses of Yeast:\tBread. The most common use of yeast has been in the making of bread. ...\tAlcoholic Drinks. Brewing wine and beer has also used yeast for centuries to ferment the mixture to make it alcoholic. ...\tNon-Alcoholic Drinks. ...\tScientific Research. ...\tBiofuel. ...\tProbiotics. ...\tYeast Extract.Mold\xa0breaks down dead substances and deposits them back into the ecosystem. Also we eat some\xa0molds\xa0such as mushrooms. Finally,\xa0molds\xa0help us create antibiotics such as penicillin and many others. Mushrooms help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil.\xa0Fungi\xa0are\xa0useful to humans\xa0because they have economic value. Some\xa0fungi, such as\xa0mushrooms\xa0and truffles, are eaten directly, and others are used to produce things of value.\xa0 | |

How metabolic reactions be explained outside the body in free cell system |
| Answer» Metabolic reactions can be demonstrated outside the body in cell-free systems. When an isolated metabolic reaction(s) is performed outside the body of an organism, in a test tube it is neither living or non-living. Hence, while metabolism is a defining feature of all living organisms without exception, isolated metabolic reactions in vitro are not living things but are living reactions. Here, it can also be said that cellular organisation of the body is the defining feature of life forms. | |

What is lymph? Write its two functions. |
|
Answer» Through the pores present in the walls of capillaries, some amount of plasma, proteins and blood cells escape into intercellular spaces in the tissues to form the tissue fluid or lymph. From intercellular spaces, it enters into lymphatic capillaries, which join to form lymph vessels, which open into larger veins. Lymph carries digested and absorbed fat from intestine and drains excess fluid from extra cellular space back into blood. Lymph 8s a yellow fluid Which provide immunity yo our body . |
