In which kind of cellular
structure would aquaporins be delivered to
their destination in the cell membrane?
Aquaporins(water channels) are part of a family of intrinsic channel proteins that form pores in the membrane of living cells and facilitate the transport of water between cells in various organisms such as bacteria, humans, plants, and fungus. Aquaporins are involved in the rapid flow of water by diffusion through the phospholipid bilayer. These aquaporins contain six membrane-spanning alpha-helical domains with both the carboxylic as well as amino terminals on the cytoplasmic side of the membrane. Aquaporins are usually always open and transport water readily through the cell membrane down its concentration gradient by simple diffusion or osmosis.
