What event triggers the release of neurotransmitters? Calcium induces the fusion of synaptic vesicles with the presynaptic membrane. Sodium induces the fusion of synaptic vesicles with the presynaptic membrane. Potassium induces the fusion of synaptic vesicles with the presynaptic membrane. Calcium activates enzymes that degrade synaptic vesicles. Sodium activates enzymes that degrade synaptic vesicles.

Step 1
When an action potential reaches the presynaptic terminal, it triggers the opening of voltage-gated calcium channels. Calcium ions then enter the presynaptic terminal and bind to proteins on the surface of the synaptic vesicles, causing them to fuse with the Show more…
