EVERYDAY SCIENCE

Detailed explanation-1: -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-2: -Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.

Detailed explanation-3: -Potential energy is stored energy and the energy of position. Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy.

Detailed explanation-4: -Chemical energy, the energy stored in chemical bonds, is thus considered a form of potential energy.
