The following are steps involved in transmission at the cholinergic synapse:1. Chemically gated ion channels on the postsynaptic membrane are opened;2. Calcium ions enter the axon terminal;3. An action potential depolarizes the axon terminal at the presynaptic membrane;4. Acetylcholine is released from storage vesicles by exocytosis;5. Acetylcholine binds to receptors on the postsynaptic membrane.The correct sequence for these events is:Question 20 Select one:4, 2, 1, 5, 3.3, 2, 4, 5, 1.2, 5, 4, 1, 3.2, 4, 1, 3, 5.1, 2, 3, 4, 5.
