In gluconeogenesis, organisms use ATP to make glucose, then in cellular respiration they break down the glucose again to get energy. Why not just store the ATP

Explanation:

So what happens is the water and carbon dioxide molecules have A chemical reaction that involves a pigment called chlorophyll which takes the suns energy and stores it. When these reactions collide they create 6 molecules o oxygen gas and 1 molecule of glucose along with  more elements. plants use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
