Quizplus · Accepted Answer

G proteins act as a switch that transmits the signal from an activated receptor to the next protein in the pathway, typically an enzyme called an effector. This process ultimately leads to the production of a cellular response, such as gene expression or contraction of muscle cells. G proteins do not bind extracellular signal molecules themselves, nor do they convert ATP to cATP or phosphorylate relay molecules in the pathway.
