Used during low-moderate intensity exercise
Aerobic Glycolysis: occurs in the sarcoplasm and is where glycogen is broken down to glucose using the enzyme glucose phosphorylase (GPP)
Glucose is catalyzed by PFK and converted to pyruvic acid. This process releases 2 ATP.
Coenzyme A forms acetyl CoA which starts the Krebs cycle as citric acid.
Krebs cycle: Co2, 2 ATP and hydrogen is produced. Occurs in the matrix.
Electron transfer chain: NAD and FAD carry hydrogen. Occurs in the cristae. 34 ATP is produced and H2O.
Food fuel: Glycogen, Glucose and fats.
Energy duration: 3 minutes onwards
