Put the following sequence in order regarding the available sources of energy in skeletal muscle. Creatine, phosphorylated by ATP to creatine phosphate by creatine kinase, provides a high energy phosphate group to energize myosin during the first 15 seconds of explosive muscle activity. Anaerobic glycolysis uses glucose to generate ATP through a series of 10 enzymatic reactions. The time it takes to get glycolysis up and running and providing ATP, including the provision of glucose through the hydrolysis of glycogen, is covered by creatine phosphate. If the muscle is operating at maximal capacity, anaerobic respiration can supply ATP for 30-40 seconds. If exercise persists for more than 30 seconds, aerobic respiration will be required to supply ATP. The reactions of oxidative phosphorylation occur in the mitochondria, require oxygen and are slower than glycolysis but supply much more ATP.

Substrate level phosphorylation involves the direct transfer of a phosphate group from substrate. It requires the presence of NADH and produces most of the ATP yield during aerobic respiration. It involves the generation of a hydrogen ion gradient to produce ATP and requires the presence of oxygen.
