The following are some of the steps in the generation of an action potential . The second gate on the voltage-gated sodium channels closes. Voltage-gated potassium channels open. Voltage-gated sodium channels reset (i.e. the gates go back to their starting positions). Chemical-gated sodium channels open. Potassium moves out of the cell. Voltage-gated sodium channels open. Small amounts of sodium ions enter the cell. Large amounts of sodium ions enter the cell. The proper sequence of these events is

The following are the steps involved in transmission at 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
