Question

Quizplus · Accepted Answer

When the alpha subunit of a G protein has GDP attached, it re-assembles with the beta and gamma subunits, no longer activates an effector protein, and can re-associate with the G protein-coupled receptor. These events are part of the cycle of activation and deactivation of G proteins in response to signals received by G protein-coupled receptors.
