KROK 1 2008 – Question 136 · KROK (Medicine) · Physiology
Rest potential of a cell equals −80 mV. At what stage of action potential did the membrane potential equal +30 mV?
- A. Depolarization
- B. After hyperpolarization
- C. After depolarization
- D. Reverse polarization
- E. -
Hint
Follow the sequence of an action potential from rest to its peak and decide which phase corresponds to a membrane potential above 0 mV, when the inside of the membrane is positive.
