A particular disease of the nervous system specifically involves the Ca²⁺ channels at the chemical synapses of motor neurons where neurotransmitter is stored and released.This disease therefore affects the A) axon terminals of the presynaptic cell and the release of acetylcholine. B) axon terminals of the postsynaptic cell and the release of K⁺. C) movement of Na⁺ out of the postsynaptic cell. D) axon terminals of the presynaptic cell and the release of K⁺. E) axon terminals of the postsynaptic cell and the release of Cl^-.

Question

Quizplus · Accepted Answer

The Ca²⁺ channels are responsible for the influx of calcium ions into the presynaptic neuron, triggering the release of neurotransmitter, specifically acetylcholine in this case. Therefore, a disease involving these channels would affect the release of acetylcholine from the axon terminals of the presynaptic cell.
