Q:

Though the equilibrium potential of Na is + 60 mV, membrane potential does not reach this value during the overshoot of the action potential because

0

Though the equilibrium potential of Na is + 60mV, membrane potential does not reach this valueduring the overshoot of the action potentialbecause:


  1. the concentration gradient of Na is reversed
  2. Na channels undergo inactivation in 1 ms
  3. voltage gated K channels open when membrane potential reaches 0 mV
  4. the membrane is impermeable to Na
  5. B+C
