A> Presence of a catalyst lowers the amount of energy needed to break the bonds.

Explanation:

Activation energy is the amount of heat or energy you must add to get the reactants to break their bonds. when on top, it will be an activated complex (point where you have added enough energy but new bonds have not yet formed.)

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
