Question

Quizplus · Accepted Answer

G protein-coupled receptors (GPCRs) are not enzymes themselves but are directly associated with an enzyme that can hydrolyze GTP. This enzyme is called a G protein and is activated by the GPCR. When a ligand binds to the GPCR, it causes a conformational change that allows the G protein to bind GTP and become active. The active G protein can then stimulate downstream signaling pathways, leading to various cellular responses.
