Problem:
Question 1: Define action potential and explain its mechanism in terms of the transient changes in Na+ and K+ permeability of the plasma membrane of a neuron. How does this action potential lead to neurotransmitter release?
Question 2: Explain the role of Na/K ATPase pumps, voltage gated Na+ and K+ channels, and Na+/Ca2+ exchanger in neurons
Please read all the questions carefully and answer them.
