Which of the following is not a function performed by a membrane protein?

Hormone binding sites

A.

B.

c.

Cell adhesion

Enzyme synthesis

Pumps for active transport

Enzyme synthesis cannot be a function performed by a membrane protein.

Explanation:

Membrane protein is found on the lipid bilayer that surrounds the cell. Enzymes are the globular structures of proteins which are made by the translation of the specific m-RNA in the cytosol of the cell and not by the membrane proteins. While a membrane protein can be used as a pump to transport ions across the membrane, it can be used for cell-cell or cell-matrix adhesion and as a hormone binding protein.
