Which ion is necessary for the release of neurotransmitter from synaptic vesicles? A) Cl⁻ B) Na⁺ C) K⁺ D) Ca²⁺

Question

Quizplus · Accepted Answer

Calcium ions (Ca2+) are crucial for the release of neurotransmitters from synaptic vesicles into the synaptic cleft. When an action potential reaches the axon terminal, it triggers the opening of voltage-gated calcium channels, allowing Ca2+ to flow into the cell and initiate the process of neurotransmitter release.
