Question

question 4 of 10 how are cellular respiration and photosynthesis related? a. all of their chemical products are gases found in the atmosphere. b. the chemical products of one are the reactants of the other. c. they both use atp energy to produce radiant energy. d. they both use light energy to produce chemical energy.

Explanation:

• For option A: Photosynthesis produces glucose (a solid) and oxygen, while cellular respiration produces carbon dioxide and water (water can be liquid). So not all products are atmospheric gases. Eliminate A.
• For option B: Photosynthesis reactants are \(CO_2\) and \(H_2O\), products are glucose and \(O_2\). Cellular respiration reactants are glucose and \(O_2\), products are \(CO_2\) and \(H_2O\). So products of one are reactants of the other. This is correct.
• For option C: Photosynthesis uses light energy to make ATP (and glucose), cellular respiration uses glucose to make ATP. They don't both use ATP to make radiant energy. Eliminate C.
• For option D: Cellular respiration does not use light energy; it uses chemical energy from glucose. Only photosynthesis uses light energy. Eliminate D.

Answer:

B. The chemical products of one are the reactants of the other.
