The principal nitrogenous exretory compound in humans is syntheisedA. in kidneys but eliminated mostly through liverB. in kidneys as well as eliminated by kidneysC. in liver and also eliminated by the same through bileD. in the liver but eliminated mostly through kidneys |
|
Answer» Correct Answer - D In humans, the principal nitrogenous excretory compound (i.e., urea) is synthesised in liver by Ornithine cycle and is eliminated mostly through kidney as nitrogeneous excretory product. In liver, one molecule of `CO_(2)` is activated by biotin and combines with two molecules of `NH_(3)` in the presence of carbamyl phosphate and one molecule of of `H_(2)O` is released. Carbamly phosphate reacts with Ornithine and forms Citrulline. Citrulline combines with another molecule of ammonia and form arginine that is broken into urea and Ornithine in the presence of an enzyme arginase and water. `2NH_(2)+CO_(2)overset("Arginase")toNH_(2)-CO-NH_(2)+H_(2)O` |

Assertion : Kidneys maintain the osmotic concentration of the blood . Reason : Kidneys eliminate either hypotonic or hypertonic urine according to the need of the body .A. If both the assertion and the reason are true and the reason is a correct explanation of the assertionB. If both the assertion and the reason are true and the reason is not a correct explanation of the assertionC. If the assertion is true but the reason is falseD. If both the assertion and reason are false |
|
Answer» Correct Answer - A (a) Kidneys play an essential role in maintaining the concentration and osmotic pressure (osmoconcentration)of blood . When water intake of an animal is very high, the urine excreted has to be hypotonic i.e., dilute and lower in omotic pressure than their blood in order to remove the excess of water contrary to this, when there is a threat of excessive water loss from the body, the urine needs to be hydertonic more concentrated and higher in osmotic pressure than their blood , to reduce the loss of the water with urine . In this way , the osmotic concentration of the bloods is maintanied . |
