The process associated with an increase in the likelihood of an action potential is called:
A)hyperpolarization
B)reuptake of neurotransmitters
C)overproduction of acetylcholine
D)depolarization

Question

Quizplus · Accepted Answer

The process described in the question - an increase in the likelihood of an action potential - is associated with depolarization. Depolarization occurs when the inside of the neuron becomes less negatively charged, which makes it more likely that an action potential will occur. A and B are incorrect because hyperpolarization decreases the likelihood of an action potential and reuptake of neurotransmitters is not directly related to the generation of action potentials. C is also incorrect because overproduction of acetylcholine could lead to excess activation of postsynaptic receptors, but it doesn't necessarily increase the likelihood of an action potential.
