What is the function of this membrane protein? A molecular view of the plasma membrane. There are two layers of phospholipids and two identical transmembrane proteins embedded in the phospholipid. The first protein has a gate that is closed and a site in the ECF where a ligand can bind. The second proteins has a ligand already bound to it and it's gate is open. What is the function of this membrane protein? a) to form the bilayer of the membrane b) linker protein c) receptor d) enzyme.

Answer: Option C (receptor)

Explanation:

The membrane protein serves as a receptor which binds to the endogenous ligand (a chemical or ion messenger) on the cell membrane triggering the opening of the cell membrane for onward passage of signals or ions into the cell. This process is called signal transduction.

The summary of functions of the membrane protein is to send the signal onward, increases the effect of a single chemical messenger (ligand), and synthesize the signal into another biochemical process.
