WebWhat do aquaporins do at the molecular level? The primary function of most aquaporins is to transport water across cell membranes in response to osmotic gradients created by active solute transport. Because the water transport capacity of aquaporin monomers is low, membranes often contain a high density of aquaporins, up to 10,000 per square ... WebJul 14, 2014 · Jul 14, 2014 Aquaporins are membrane proteins that serve as channels in the transfer of water, and in some cases, small solutes across the cell membrane. The channels are so selective that water passes through them, and acid does not. They are found in bacteria, plants, and animals. how hypokalemia cause digoxin toxicity
