Cellular respiration consists of many steps, not just a single reaction.
Cellular respiration can produce up to 32 ATP molecules for each glucose molecule, a capture of about

If ATP could not be regenerated through cellular respiration, you
would use up nearly your body weight in ATP each day.

necessary during vigorous exercise?
