The resting membrane potential of a neuron is approximately . If the membrane potential changes to , what is the most likely outcome?
- A.Hyperpolarization of the membrane
- B.Inhibition of the sodium-potassium pump
- C.Generation of an action potential
- D.Closure of all voltage-gated channels
Show correct answer & step-by-step solution
Correct answer: C — Generation of an action potential
Solution
- The threshold potential for a typical neuron is approximately .
- Depolarization to this threshold triggers the opening of voltage-gated channels.
- Rapid influx of leads to the generation of an action potential.
- Hence the answer is (C).
