Answer:
The correct answer is The process of photosynthesis is energy storing reaction because the process converts light energy into chemical energy which is stored in the bonds of glucose.
Explanation:
Photosynthesis is an important pathway occur in the mesophyll tissue of leaves of plants . Photosynthesis helps in formation of glucose molecule that is stored as polysaccharide starch inside the plant"s body.
        During photosynthesis light energy is captured from sun by the antenna complex of photosystem then the light energy is transferred to the reaction center for its conversion into chemical energy in form of ATP molrcules.
      The so formed ATP molecules helps in the biosynthesis of glucose by various enzyme catalyzed reactions.
