Question

Quizplus · Accepted Answer

Calcium influx into the presynaptic axon terminal is necessary for the release of neurochemicals, such as neurotransmitters, which are responsible for transmitting signals across the synapse to the postsynaptic neuron. Therefore, the greater the influx of calcium, the greater the release of neurochemicals. None of the other options are directly related to calcium influx in this context.
