When your body breaks down sugar completely, how much heat in released compared to burning the same amount of sugar in a flame?
a. the body releases more heat.
b. the body releases less heat.
c. the body releases the same amount of heat.
d. the body releases no heat.

The correct option is c.

Explanation:

According Hess's law of Constant heat summation;

The change in enthalpy of the reaction remain the same for the reaction carried out in single step or in multiple steps.

So, when sugar breaks down completely in our body it goes through series of  chemical reactions in which small amount of energy is released in each and every step.

Sugar →  A

B → C

C → D

Small amount of energy is released during each steps.

But when same amount of sugar is burnt in flame will same amount energy given by the breakdown of sugar in our body.

A  → D

Hence, the correct answer is option c.

if you mean hydrogen and oxygen then water is the product
