Depolarization in action potential mainly occurs due to entry of which ion?
Action potential में depolarization मुख्य रूप से किस ion के अंदर आने से होती है?
Show answer and explanation
Correct Answer
A. sodium ion
Explanation
Step 1: Identify nerve impulse phase. Step 2: When sodium channels open Na plus enters the neuron and membrane potential becomes less negative. Step 3: Remember depolarization equals sodium entry.
Step 1: nerve impulse phase पहचानें। Step 2: Sodium channels खुलने पर Na plus neuron में आता है और membrane potential less negative होता है। Step 3: Depolarization equals sodium entry याद रखें।
