Question

examine the model depicting the relationship between photosynthesis and cellular respiration. select all of the choices that correctly pairs products and reactants with their place in the model. a a atp b b water and oxygen c b water and carbon dioxide d b carbon dioxide and atp e d oxygen and glucose

Explanation:

To solve this, we recall the equations of photosynthesis and cellular respiration:

• Photosynthesis: \( \text{6CO}_2 + \text{6H}_2\text{O} \xrightarrow{\text{light energy}} \text{C}_6\text{H}_{12}\text{O}_6 + \text{6O}_2 \) (reactants: \( \text{CO}_2, \text{H}_2\text{O} \); products: \( \text{C}_6\text{H}_{12}\text{O}_6, \text{O}_2 \)).
• Cellular Respiration: \( \text{C}_6\text{H}_{12}\text{O}_6 + \text{6O}_2

ightarrow \text{6CO}_2 + \text{6H}_2\text{O} + \text{ATP} \) (reactants: \( \text{C}_6\text{H}_{12}\text{O}_6, \text{O}_2 \); products: \( \text{CO}_2, \text{H}_2\text{O}, \text{ATP} \)).

Now, analyze each option:

• Option A: ATP is a product of cellular respiration, not a direct “place” in the photosynthesis - respiration model (vague pairing). Eliminate.
• Option B: Water and oxygen are products of photosynthesis? No—oxygen is a product, but water is a reactant in photosynthesis. Incorrect.
• Option C: Water and carbon dioxide are products of cellular respiration (matches the respiration equation). Correct.
• Option D: Carbon dioxide is a reactant in photosynthesis, ATP is a product of respiration—incorrect pairing. Eliminate.
• Option E: Oxygen and glucose are products of photosynthesis (matches the photosynthesis equation). Correct.

Answer:

C. C: water and carbon dioxide
E. E: oxygen and glucose
