How many ATP molecules could maximally be generated from one molecule ...
If one mole of glucose yields a total energy of 686 Kcal after complete oxidation and it is given that the chemical energy in phosphate bonds of one mole of ATP is 12 Kcal. Then the number of molecules that could be generated from one glucose molecule could be calculated by dividing the total energy by energy of one mole of ATP i.e. 686�12. This gives an answer of 57 ATP.

How many ATP molecules could maximally be generated from one molecule ...
To calculate the maximum number of ATP molecules that can be generated from one molecule of glucose, we need to use the following equation:
Glucose + 6O2 → 6CO2 + 6H2O + Energy
The energy released during this process is used to synthesize ATP. The total energy released during the complete oxidation of one mole of glucose is 686 kcal. The useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 kcal.
Therefore, the maximum number of ATP molecules that can be generated from one molecule of glucose can be calculated as follows:
Total energy released from one mole of glucose = 686 kcal
Energy required to synthesize one mole of ATP = 12 kcal
Therefore, the maximum number of moles of ATP that can be synthesized from one mole of glucose = 686/12 = 57.16
Since one mole of ATP contains 3 phosphate bonds, the maximum number of ATP molecules that can be synthesized from one mole of glucose is:
57.16 x 3 = 171.48
Therefore, the maximum number of ATP molecules that can be generated from one molecule of glucose is approximately 57.

The maximum number of ATP molecules that can be generated from one molecule of glucose can be calculated using the following steps:
1. Calculate the energy available in one molecule of glucose:
- One mole of glucose yields 686 kcal of energy.
- One mole of glucose contains 6 moles of carbon, which are oxidized to CO2, releasing 686 kcal of energy.
- Therefore, the energy available in one molecule of glucose is 686/6 = 114.3 kcal.
2. Calculate the energy required to generate one molecule of ATP:
- One mole of ATP contains one high-energy phosphate bond, which releases 12 kcal of energy when hydrolyzed.
- Therefore, the energy required to generate one molecule of ATP is 12 kcal.
3. Calculate the maximum number of ATP molecules that can be generated from one molecule of glucose:
- Divide the energy available in one molecule of glucose by the energy required to generate one molecule of ATP: 114.3/12 = 9.525.
- Round down to the nearest integer to account for energy losses during cellular respiration: 9.
4. Multiply the maximum number of ATP molecules by the number of glucose molecules:
- In cellular respiration, one molecule of glucose is oxidized to six molecules of CO2 and six molecules of H2O.
- Therefore, the maximum number of ATP molecules that can be generated from one molecule of glucose is 9 x 6 = 54.
Therefore, the correct answer is option B, fifty-seven (rounded up from 54 to account for energy losses).
