Which of the following statements is true about photosynthesis and cellular respiration?

• A. Cellular respiration produces glucose, while photosynthesis breaks it down.
• B. Both photosynthesis and cellular respiration occur only in animal cells.
• C. Photosynthesis converts light energy into chemical energy, while cellular respiration releases energy from chemical compounds.
• D. Photosynthesis requires oxygen as a reactant, while cellular respiration releases oxygen as a product.

Answer: (C)

Verified step by step guidance

1. Step 1: Begin by understanding the processes of photosynthesis and cellular respiration. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. Cellular respiration is the process by which cells break down glucose to release energy in the form of ATP.
2. Step 2: Analyze the first statement: 'Cellular respiration produces glucose, while photosynthesis breaks it down.' This is incorrect because photosynthesis produces glucose, while cellular respiration breaks it down to release energy.
3. Step 3: Analyze the second statement: 'Both photosynthesis and cellular respiration occur only in animal cells.' This is incorrect because photosynthesis occurs in plant cells, algae, and some bacteria, while cellular respiration occurs in both plant and animal cells.
4. Step 4: Analyze the third statement: 'Photosynthesis converts light energy into chemical energy, while cellular respiration releases energy from chemical compounds.' This is correct because photosynthesis uses light energy to synthesize glucose, and cellular respiration breaks down glucose to release energy.
5. Step 5: Analyze the fourth statement: 'Photosynthesis requires oxygen as a reactant, while cellular respiration releases oxygen as a product.' This is incorrect because photosynthesis requires carbon dioxide and water as reactants and releases oxygen as a product, while cellular respiration uses oxygen as a reactant and releases carbon dioxide as a product.
