Question

Is there more energy in one molecule of ATP or on molecule of sugar?

Answer 1

The molecule of sugar has more energy.

Explanation:

Given that the oxidation of, for example, glucose (`C_6H_12O_6`) by cellular respiration can produce `38` ATP, it would follow that there is more energy in a molecule of sugar than a molecule of ATP.

`DeltaG_("oxidation of glucose")=-686" kcal/mol"`

`DeltaG_("hydrolysis of ATP")=-7.3" kcal/mol"`
