Question

What is role of proteins in active transport, facilitated diffusion? what are names of these proteins? so much confusing?

Answer 1

There are two strategies in transport: active transport and passive transport.

Explanation:

Various transmembrane proteins play important role in transport. Transmembrane proteins resides in lipid moiety of the cell membrane because it helps in the movement of solute from outside and inside vice versa. Any charged molecule can not cross the cell membrane so that facilitation is required.In passive transport also called facilitated diffusion where transport of solute take place along the concentration such as GLUT transport for glucose uptake from blood.No energy requirement here.In active transport where solute transport take place against the concentration, energy is needed in the form of ATP for active transport. such as:sodium and potassium pump, some channel proteins such as chloride channels.
