The total amount of neurotransmitter released at the axon terminal is directly related to
A) the amplitude of the action potential.
B) the length of the axon.
C) the total number of action potentials.
D) the amplitude of the graded potential.

Question

Quizplus · Accepted Answer

The total amount of neurotransmitter released at the axon terminal is directly related to the total number of action potentials. This is because each action potential triggers the release of a fixed amount of neurotransmitter. Therefore, the more action potentials that occur, the more neurotransmitter is released. A and D are not correct because the amplitude of the action potential or graded potential does not directly affect the amount of neurotransmitter released. B is also not correct because the length of the axon does not play a significant role in determining the amount of neurotransmitter released.
