When a hormone molecule binds to a specific protein on the plasma membrane, the protein it binds to is called a
A) ligand.
B) clathrin.
C) receptor protein.
D) hydrophobic protein.
E) cell adhesion molecule.

Question

Quizplus · Accepted Answer

When a hormone molecule binds to a specific protein on the plasma membrane, the protein is called a receptor protein. Ligands are molecules that bind to a receptor, clathrin is a protein involved in endocytosis, hydrophobic proteins are not necessarily involved in hormone signaling, and cell adhesion molecules are involved in cell-cell adhesion, not hormone signaling.
