Expert Solution

Introduction:

Receptors are protein structures that transduce signals in cells when a ligand binds to them. The receptor undergoes a conformational change after a ligand binds to it, allowing it to relay signals inside the cell.

Types of receptors include:

Intracellular receptors
Cell surface receptors
G-protein coupled receptors (GPCRs)
Tyrosine kinase receptors
Ligand-gated ion channels

A substance that binds to a receptor to promote a process is known as an agonist. An antagonist is a chemical that inhibits the signal transduction process by binding to the same receptor.
