Question

according to the all - or - none law, what would happen if a neuron were depolarized by twice the normal amount needed to produce an action potential? multiple choice nothing would happen, because the cell must be polarized to fire. the action potential would not be affected by the strength of the depolarization. the strength of the action potential would be proportionate to the depolarization. the action potential would have an inhibitory effect on the next neuron.

Explanation:

The all-or-none law of action potentials states that once the threshold for depolarization is reached, an action potential is triggered at a fixed magnitude, regardless of how much the stimulus exceeds the threshold. Extra depolarization beyond the threshold does not change the action potential's strength or characteristics.

Answer:

B. The action potential would not be affected by the strength of the depolarization.
