When an action potential reaches the axon terminal, the ____ channels are activated to trigger synaptic vesicle release. A) voltage-gated Cl^-channels B) voltage-gated Ca²⁺channels C) voltage-gated Na⁺channels D) ligand-gated Cl^-channels E) ligand-gated Ca²⁺channels

Question

Quizplus · Accepted Answer

When an action potential reaches the axon terminal, voltage-gated calcium (Ca2+) channels are activated, leading to an influx of calcium ions which triggers the release of neurotransmitters from synaptic vesicles into the synaptic cleft.

When an Action Potential Reaches the Axon Terminal, the ____
