nutrient that we consume have chemical energy  stored within their chemical bond. This  nutrient molecules are our main source of energy for metabolism.

chemical energy is potential of chemical substances to undergo transformation through a chemical reaction to transform other chemical substance. food energy is released during digestion whereby molecules in our food are broken into smaller pieces.As bond between these atom loses a chemical reaction occurs.

they are c. hope this !
