Detailed explanation-1: -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-2: -According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds. Energy is absorbed to break bonds, and energy is evolved as bonds are made.

Detailed explanation-3: -It takes energy to break bonds. Energy is released when bonds are formed.

Detailed explanation-4: -A chemical digestion process called enzymatic hydrolysis can break the bonds holding the molecular ‘building blocks’ within the food together. For example, proteins are broken down into their ‘building block’ amino acids.

Detailed explanation-5: -Chemical energy in food As the bonds between the atoms in food loosen or break, a chemical reaction takes place, and new compounds are created. The energy produced from this reaction keeps us warm, helps us move, and allows us to grow. Different foods store different amounts of energy.
