The opening of stimulus-gated channels is always followed by the opening of voltage-gated channels.

Question

Quizplus · Accepted Answer

The opening of stimulus-gated channels and the opening of voltage-gated channels are two separate and distinct events. One does not necessarily always follow the other. Stimulus-gated channels open in response to a specific stimulus, such as a neurotransmitter binding to a receptor, while voltage-gated channels open in response to a change in membrane potential. These two types of channels may interact in different ways depending on the specific physiological context, but the opening of one is not always dependent on the opening of the other.
