Question

what type of energy is associated with food? how is that energy stored? how does food energy change when it is used to do work

Answer 1

Chemical energy is associated with food. It is stored in the chemical bonds of atoms and molecules. It can only be seen when it is released in a chemical reaction. When chemical energy is released, the substance from which the energy came is often changed into a different substance. When the stomach digests food, the carbohydrate in the food breaks down into another type of sugar called glucose.
