Aerobic ATP Production & Energy System Efficiency

Aerobic ATP Production & Energy System Efficiency

Aerobic ATP production, which occurs predominantly during prolonged low-moderate intensity exercise, is the oxidation (breakdown) of glucose/glycogen (called glycolysis), lipids (triglycerides; called lipolysis), and proteins (amino acids; called proteolysis) into acetyl CoA, which enters the Krebs Cycle, where hydrogen removal occurs and the electron transport chain inside the mitochondria of the muscle cell provides the...
