Question

What are the functions of transmembrane proteins?

Answer 1

Transmembrane proteins basically function as gates or docking sites that allow or prevent the entry or exit of materials across the cell membrane.

Explanation:

These are proteins that are situated in the lipid membrane of the cells. Transmembrane proteins carry either endogenous compounds or xenobiotics across biological membranes.

The two main forms of transmembrane proteins are channels and carriers. Certain specialised transmembrane proteins known as G protein-coupled receptors serve as cell surfaces switches to transmit extracellular signals into cells.
