At any given moment, approximately how much energy is stored in the human body as ATP in the ADP-P-bond?
This of course depends on what type of cell it is and the activity of the individual in question. The calculation should be fairly simple, as we know that ATP hydrolysis release about 30 kJ/mol. Hence, the question could actually be re-phrased to $"$At any given moment, how much ATP does the human body have?$"$
