Aquaporins (AQP) are integral membraneproteins that serve as channels in thetransfer of water, and in some cases, smallsolutes across the membrane.A.TrueB.False

Aquaporins are channels that allow to travel across plasma membranes.

The binding of ADH to principal cells causes vesicles with aquaporin proteins to migrate to the interior of the cells.True false question.TrueFalse

Which of the following hormones affects the rate of reabsorption of water in the collecting duct of the nephron by regulating the insertion of aquaporins into cell membranes?

For each statement, indicate whether it is true or false Osmosis is the active transport of water across a selectively permeable membrane.    Aquaporins increase membrane permeability to water in some cell types, such as kidney cells.   During osmosis, water moves from a solution with proportionately more water across a selectively permeable membrane into a solution with proportionately less water.   Osmotic pressure is the force that assists water in moving by osmosis across a selectively permeable membrane.   The greater the concentration of a solution (the less water it has), the greater the tendency for water to move into the solution, and the greater the osmotic pressure to prevent that movement.
