Adh also causes the epithelial cells that line the renal collecting tubules to move water channel proteins, called aquaporins, from the interior of the cells to the apical surface, where these proteins are inserted into the cell membrane. the result is an increase in the water permeability of these cells and, thus, a large increase in water passage from the urine through the walls of the collecting tubules, leading to more reabsorption of water into the bloodstream.. Aquaporins removed from tubule membrane and are enclosed in vesicles collecting duct impermeable to water large amounts of dilute urine. In order to maintain homeostasis in the body, there is a need to balance water output and water input. water intake comes from liquids, food. the major ways by which water is lost from the body are urine, sweat, feces, a diffusion that occurs through the skin, etc. urine is produced manufactured by the kidney and it accounts for the largest amount of water that leaves from the body..
Ex. plant cells, kidney cells, and red blood cells) 33: 1045203503: why are aquaporins important in kidney cells? kidney cells must reabsorb a large amount of water when producing urine: 34: 1045203504: active transport: a cell must expend energy to move a solute against its concentration gradient across a membrane toward the side where the. When water intake is low, humans and other higher organisms produce very small quantities of urine. "to help the body retain as much fluid as possible, water is reabsorbed from urine within the. Kidney cells must reabsorb a large amount of water when producing urine. active transport a cell must expend energy to move a solution against its concentration gradient - that is, across a membrane toward the side where the solute is more concentrated..
