17 pts ! the chemical equation shown represents photosynthesis. carbon dioxide + a + light > b + oxygen. what is the role of substance b in photosynthesis? a. it stores chemical energy. b. it converts light into chemical energy. c. it traps light energy from the atmosphere. d. it cools the atmosphere by changing into vapor.

A. It stores chemical energy.

Explanation:

B here is nothing but glucose (C₆H₁₂O₆). Glucose is the ultimate product of photosynthesis. During photosynthesis, light energy of sun is converted into chemical energy which is stored in the chemical bonds of food (carbohydrate which is a polymer of glucose).

In the photosynthetic reaction, carbon dioxide molecule (CO₂) and water (H₂O) molecule react in the presence of sunlight to produce glucose and oxygen (O₂). The reaction is written as under:

                                Sunlight

6 CO₂  +   6 H₂O          →             C₆H₁₂O₆+ 6 O₂
