Which of the following most accurately represents the order of events for transmission at a G-protein coupled receptor?
A) Activation of a G-protein, binding of the neurotransmitter, activation of the effector
B) Binding of the effector, binding of the neurotransmitter, activation of a G-protein
C) Binding of the neurotransmitter, activation of a G-protein, activation of the effector
D) Activation of the effector, binding of the neurotransmitter, activation of a G-protein
E) Binding of a G-protein, binding of the neurotransmitter, activation of the effector

Question

Quizplus · Accepted Answer

The correct sequence for transmission at a G-protein coupled receptor is: binding of the neurotransmitter to the receptor, which then activates a G-protein, followed by the activation of an effector enzyme or ion channel. This sequence ensures the proper transmission of signals across the cell membrane.
