Question

Quizplus · Accepted Answer

A ligand is a molecule that binds to a protein, such as an ion channel. A receptor is a protein that binds to a ligand, so it is not the general term for a molecule that binds to a protein. Second messengers are intracellular signaling molecules, so they are not necessarily molecules that bind to proteins. Amine is a type of organic compound and not a general term for a molecule that binds to a protein.
