HUMAN NUTRITION

Detailed explanation-1: -Answer and Explanation: The correct answer: Organic molecules store potential energy in covalent bonds. Organic molecules are present in the body like the nutrients that are absorbed from the food. The organic molecules are formed with the help of covalent bonds and the bonds in their structure carry the energy.

Detailed explanation-2: -The potential energy of chemical energy is found stored in the chemical bonds that bind atoms in molecules. Breaking these bonds apart or reforming them by adding fuels or reactants releases the chemical energy in the bonds. We call this breaking and forming of bonds a chemical reaction.

Detailed explanation-3: -Proteins, lipids, carbohydrates, and nucleic acids are the most common long-term energy storage molecules in cells. All four are organic compounds and are much larger in size than ATP molecules. Energy is stored in the chemical bonds of energy storage molecules and is released when these chemical bonds are broken.
