Question

Quizplus · Accepted Answer

Adenylate cyclase is the enzyme responsible for converting ATP to cyclic AMP (cAMP) in response to a signal. In the context of a slow excitatory postsynaptic potential, the closure of potassium channels can be mediated by cAMP, which is produced by adenylate cyclase. This process typically involves a G protein-coupled receptor that activates adenylate cyclase upon stimulation.
