Definitions:

Enzyme-linked Receptors

A class of cell surface receptors that initiate a cellular response upon binding a specific ligand, often leading to a series of enzymatic reactions inside the cell.

Ion Channel-linked Receptors

Proteins that span a cell membrane and open to allow ions such as Na+, K+, Ca2+, and Cl- to pass in response to the binding of a chemical messenger.

G Protein-linked Receptors

Proteins that transmit signals from outside the cell to the inside by binding with G proteins, initiating various cellular processes.

Second Messenger

Intracellular signaling molecules released by the cell in response to exposure to extracellular signaling molecules.
