Document Content and Description Below

A runner has depleted all the oxygen available for muscle energy. Which of the following will facilitate his continued muscle performance? Anaerobic glycolysis What causes the rapid change in the resting membrane potential that initiates an action potential? Sodium gates open, and sodium rushes into the cell, changing the membrane potential from negative to positive. A 12-year-old male is diagnosed with Klinefelter syndrome.
