Problem
How do you think exercise training might influence the number of sodium potassium (Na+/K+) exchange pumps in the membrane of a skeletal muscle, what impact might this have on the function of that muscle? Describe in detail the function of a Na+/K+ exchange pumps in an excitable skeletal muscle cell, include a description of its importance in maintaining skeletal muscle function. What would happen if the sodium potassium exchange pump stopped working?
