Question

What are aquaporins

Answer 1

Aquaporins are integral membrane proteins that serve as channels in the transfer of water, and in some cases, small solutes across the membrane. They are conserved in bacteria, plants, and animals. Structural analyses of the molecules have revealed the presence of a pore in the center of each aquaporin molecule.
Hence, they are called aqua (because of water chaneling properties) and porin (because of pores in it).
