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: -ATP stands for adenosine triphosphate. The word triphosphate indicates that the molecule has 3 phosphate groups. ATP stores energy within the bonds between phosphate groups, especially the second and third. This bond is a source of potential chemical energy, and it’s kind of like a compressed spring.

Detailed explanation-3: -Although the photosynthetic process, which is carried out in the chloroplasts present in plant cells, involves numerous steps, it can be summarised in the following equation. This reaction only proceeds with an input of solar energy, and the product glucose stores this energy as chemical potential energy.

Detailed explanation-4: -Answer and Explanation: a) Glucose contains the most potential energy.
