Answer:
In the electron transport chain, when the protons move down their concentration gradient, the electrons are transferred from one molecule to the other and energy is released.
Explanation:
During the rear stage of cell respiration or oxidative phosphorylation two processes are involved. Among which one is the electron transport proton gradient chain, in which protons are transferred from one to the other molecule.
In this process electron also releases energy to make an electrochemical gradient. In this chain oxygen accepts protons and chooses electron to produce water.
ADH increases the permeability of the collecting duct to water, and this means water flows from the Collecting duct into the blood to decrease the volume of the fluid in the collecting duct.
ADH is a hormone that increases permeability to water in the collecting ducts and therefore increases water reabsorption from the urine. This decreases the volume of water in the urine.
ADH travels in the bloodstream to its target organ, the kidneys. It causes the kidney tubules to become more permeable . This means more water can leave the kidney tubule to be reabsorbed back into the blood during selective reabsorption.
