The average human (you will have to figure out what that is) produces her/his weight in ATP per 24 hours day, but at any one time, the human body has only a reserve of about 250g of ATP. Obviously, a lot of ATP is being used up all the time, and it ahs to be replaced. Calculate roughly how many ATP molecules the average human cell produces per second. To determine what the average cell is, you will have to discover the number of cells produces per second. To determine what the average cell is, you will have to discover the number of cells in the average human body, and how much the average human weighs. (It is obvious that some cells are more active thant others, but for the sake of this exercise, assume all cells are equally active.)

Solution

We need to look into the fact of average cell- The number of cells in the average human body with the average human weight. An average person , an adult is weighing 60kgs has to produce a number of ATP in the cell that cach day the person produces. ATP is a long term storage, hence every day the average person will consume ATP produced from food/fat.

An average person, lets say a women needs to burn about 1600 Kcal of fuel each day. Each mole of ATP releases about 8Kcal of energy. Now for instance weight of one molecule of water is 18amu, so 6.02 * 10²³ molecule of water, it would be 18 grams then. Average human body will produce approximately 10¹⁴ cells.

1600 Kcal/day / 8 Kcal /mol = 200 mol ATP/day.

We can convert this to second from the day.

200 mol / day / 86400 sec / day = 2.3 x 10^-3 mol ATP / sec.

2.3 x 10 ^-3 mol / sec x 6.02 x 10²³ molecule/ mol = 1.4 x 10²¹ molecule / sec.

Now the rate for a average human body will be 10¹⁴ cells -- 10⁷ (10 million) ATP molecules / sec / cell.
