A decrease in the number of voltage-gated Ca²⁺ ion channels in the presynaptic terminal would A) enhance transmission across the synapse. B) reduce or inhibit transmission across the synapse. C) have no effect on transmission across the synapse. D) alter receptors on the postsynaptic membrane. E) increase exocytosis.

Question

Quizplus · Accepted Answer

A decrease in the number of voltage-gated calcium ion channels in the presynaptic terminal would reduce or inhibit transmission across the synapse because these channels are crucial for triggering neurotransmitter release through exocytosis.

A Decrease in the Number of Voltage-Gated Ca2+ Ion Channels
