Question

When more action potentials arrive at the axon terminal, how is the postsynaptic cell affected?

A. Neurotransmitter release increases, but does not change the graded potentials that follow.

B. Neurotransmitter release does not change, thus the postsynaptic cell behaves the same way it always behaves.

C. Neurotransmitter release increases, thereby increasing the frequency or magnitude of graded potentials in the postsynaptic cell.

D. Neurotransmitter release does not change, but voltages applied to the postsynaptic cell increase.

Answer 1

When more action potentials arrive at the axon terminal, the postsynaptic cell is affected by an increase in neurotransmitter release, resulting in an increase in the frequency or magnitude of graded potentials in the postsynaptic cell.

Step-by-step explanation:

When more action potentials arrive at the axon terminal, the postsynaptic cell is affected by an increase in neurotransmitter release. This increase in neurotransmitter release can lead to an increase in the frequency or magnitude of graded potentials in the postsynaptic cell. Therefore, the correct answer is option C. Neurotransmitter release increases, thereby increasing the frequency or magnitude of graded potentials in the postsynaptic cell.
