The fоllоwing аre the steps invоlved in trаnsmission аt a synapse . 1. Chemically gated sodium channels in the postsynaptic cell open. 2. Calcium ions enter the presynaptic cell. 3. Proteins hydrolyze (break down) neurotransmitter. 4. An action potential reaches the end of the presynaptic cell. 5. The synaptic knob reabsorbs neurotransmitter. 6. Neurotransmitter is released from vesicles by exocytosis. 7. Neurotransmitted binds to receptors in the postsynaptic cell. The correct sequence for these events is
