Q. ID – 13022021

Action potential is occoured by :

  1. Sodium-Potassium pump
  2. Rapid influx of Sodium ions
  3. Eflux by diffusion of Potassium ions
  4. Influx of Calcium ions

Answer : 2nd Option

Explanation :
→ In a polarise membrane Sodium-Potassium pump always have opened except depolarisation, actively transport 3 Na+ outwards for 2 K+ into the cell, established Resting potentials of the membrane.
→ During depolarisation of the polarised resting membrane, Na+ influx rapidly and occour Action Potential.
→ Eflux of K+ by passive diffusion estabilished resting potential.
→ Ca+2 not involve action potential.
