If the graded potential increases in amplitude, then the frequency of the action potentials fired also increases.

Question

Quizplus · Accepted Answer

The amplitude of the graded potential is directly proportional to the frequency of action potentials. As the graded potential increases in amplitude, it depolarizes the membrane to a greater extent, which increases the likelihood that the membrane potential will reach the threshold for firing an action potential. Therefore, the frequency of action potentials fired will increase.

If the Graded Potential Increases in Amplitude, Then the Frequency
