Explanation:
Action potential in contractile cells can be divided into 3 phases
1. Rapid depolarization; caused by fast influx of sodium ions into the cells. Last a few milliseconds.
2. Plateau phase: This is a sustained positive membrane potential, after rapid depolarization, caused by a balance between calcium ion influx and slow potassium ion efflux.
3. Rapid repolarization: Eventually there's a closure of all other ion channels except the potassium ion channels causing rapid efflux of potassium ions, returning the membrane potential back to negative.
A refractory period usually occurs after undergoing an action potential. During this time no action potential can occur.
Answer: All are multicellular and eukaryotes.
