True about relative refractory period is:
Response can't be generated at all
Due to closure of inactive gates of sodium channals
Due to opening of potassium channals
All
Stronge stimulus can produce response in relative refractory period Cause: it is because potassium channals are open and the membrane potential is more close to resting membrane Begins after the end of absolute refractory period Ref:Guyton and Hall textbook of medical physiology 12th edition,page number: 70
