... I. There are two different subtypes of ACh receptors: nicotinic and muscarinic. A. Nicotinic receptors enclose membrane channels and open when ACh bonds to the receptor. This causes a depolarization called an excitatory postsynaptic potential (EPSP) in skeletal muscle cells. B. The binding of ACh to ...
