Roughly what percentage of the ATP required by a resting or moderately active muscle is supplied by aerobic respiration?

1. Aerobic respiration breaks down glucose or other nutrients with oxygen to produce carbon dioxide, water, and ATP in the mitochondria. 2. Because it is far more efficient per glucose molecule than glycolysis, it dominates ATP supply at rest. 3. Approximately 95 percent of the ATP required for resting or moderately active muscle comes from aerobic respiration. 4. 36 ATP per glucose is aerobic respiration's yield per molecule, a different figure from its percentage share of total ATP supply. 5. 50 percent understates how dominant aerobic respiration actually is at rest. 6. 15 percent understates it even further, closer to what anaerobic pathways alone might contribute. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 10 "Muscle Tissue", section 10.3, p. 420_
