Aerobic respiration is the process that breaks down sugars to make ATP when oxygen is present. It occurs in the mitochondria and provides most of the ATP needed for resting or moderately active muscles.
Aerobic respiration is the process that breaks down sugars to make ATP when oxygen is present. This process occurs in the mitochondria and is responsible for approximately 95% of the ATP required for resting or moderately active muscles. Glycolysis is another process that can generate ATP, but it is an anaerobic process that does not require oxygen.
