Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where does food store chemical energy?
A
in the bonds
B
in the elements (C, H, O, etc)
C
in the protein
D
in the fat
Explanation: 

Detailed explanation-1: -Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules.

Detailed explanation-2: -At the most fundamental level, chemical energy is stored in food as molecular bonds. These molecular bonds represent potential energy, which is either very stable, such as in fat molecules, or very active and transitory, such as in ATP molecules.

Detailed explanation-3: -Our approach to bond energies and thermochemistry is to emphasize that energy is stored in a system of molecules (rather than in a particular molecule).

Detailed explanation-4: -Answer and Explanation: Chemical bonds contain potential energy. This energy is stored in covalent bonds that have the potential to hold various atoms together in order to form a molecule.
