# At any given moment, how much energy is stored in the human body as ATP?

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?$"$

• how much googling have you done? I'd start with "how many ATP molecules in human body" and then multiply that estimate by 30kJ/mol Jan 19 '16 at 15:48
• All I can find is how much ATP the human body uses per time unit. I'm not seeking that but rather how much present ATP there is at a given time. Jan 19 '16 at 15:52
• that is generally expected that you'll add what you;ve found to your question. Is makes it much better Jan 19 '16 at 16:01
• what do you think of following approximation: ATP is not a long-term storage hence every day you consume all ATP you produced from food/fat. That means that on average day-to-day you have X mol ATP/min * 24 hr? where X is the number of ATP/min body burns. Jan 19 '16 at 16:04
• I'm not looking for that either. If you froze time and started to count all ATP molecules in a human body, that's the number. Jan 19 '16 at 17:05
