Using the reactants and products of Photosynthesis and Cellular Respiration describe the relationship between the two

Refer to bolded below

Explanation:

Photosynthesis involves carbon dioxide and water as the reactants, combining to form glucose and oxygen ( the products ).

Now there is dark photosynthesis and light photosynthesis, where light photosynthesis takes place first considering it converts carbon dioxide (CO2) and water (H2O) into carbohydrates. The ATP energy from the light photosynthesis helps the dark photosynthesis produce the sugars.

Cellular Respiration is simply the opposite. Taking the reactants and products into account, you could simply switch the two and the reactants of photosynthesis = products of cellular respiration, and vice versa. However, ATP energy is made in both. In fact Photosynthesis actually uses some ATP energy in it's chemical reaction...

Thus, we can conclude that Photosynthesis is quite the opposite of Cellular Respiration ( in terms of their chemical formula )

the answer is b.) hydrogen bonds between bases.
