Skeletal Muscle Action Potential – Part 2 Take a look again at the graph of an action potential on the sarcolemma of a skeletal muscle cell (given below). Describe what is happening at a molecular level to generate the depolarization and repolarization phases. Make sure to include in your answer: which ions are moving, in what direction each ion is moving, and what kind of channel each ion is moving through.
