Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Describe what happens to these four substances during photosynthesis

Explanation:

Photosynthesis is a light catalyzed chemical reaction that occurs in nature by all plants.

The process involves the reaction between carbon dioxide and water in the presence of sunlight.

This in turn produces glucose and oxygen gas.

             6CO₂  +   6H₂O   →  C₆H₁₂O₆  + 6O₂

So, food is produced at the end of the reaction in form of glucose. In terms of energy, light energy is transformed into chemical energy stored in glucose.

substitution is the answer in this case

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
