A single action potential in a motor neuron is sufficient to produce an action potential in a skeletal-muscle fiber. Table 11-2 summarizes the events leading to the contraction of a skeletal-muscle fiber. Muscle fibers form ATP by the transfer of phosphate from creatine phosphate to ADP, by oxidative phosphorylation of ADP in mitochondria, and by substrate-level phosphorylation of ADP in the glycolytic pathway. 2  At the beginning of exercise, muscle glycogen is the major fuel consumed.
