What does a receptor protein do? a. allows one or a few specific molecules to pass across the membrane b. allows a specific molecule to bind to it because of its shape c. allows the body to distinguish between its own and other cells d. allows cell-to-cell adhesion and communication

Receptor receives chemical signals came from the cell's outside environment. It is made up of protein molecule. The correct answer for the question above is letter a. Receptor protein allows one or a few specific molecules to pass across the membrane.

A Receptor Protein has a shape that allows a specific Molecule, called a signal molecule to bind to it. There for the answer would be B.
