Question

Quizplus · Accepted Answer

When a ligand binds to a membrane receptor protein, it causes a conformational change in the receptor protein. This change allows the receptor to interact with other proteins and initiate a signal transduction pathway. The activation of intracellular enzymes or G proteins occurs later in the pathway. The membrane receptor protein does not enter the cytoplasm; it remains embedded in the membrane.
