Which statement about cellular respiration is true?

• A. Cellular respiration occurs only in plant cells.
• B. Cellular respiration produces glucose from carbon dioxide and water.
• C. Cellular respiration converts glucose and oxygen into carbon dioxide, water, and ATP.
• D. Cellular respiration takes place exclusively in the cytoplasm of eukaryotic cells.

Answer: (C)

Verified step by step guidance

1. Step 1: Begin by understanding the concept of cellular respiration. Cellular respiration is a metabolic process that occurs in cells to convert glucose and oxygen into energy in the form of ATP, along with byproducts like carbon dioxide and water.
2. Step 2: Evaluate the first statement: 'Cellular respiration occurs only in plant cells.' This is incorrect because cellular respiration occurs in both plant and animal cells, as all eukaryotic cells require energy to function.
3. Step 3: Evaluate the second statement: 'Cellular respiration produces glucose from carbon dioxide and water.' This is incorrect because this describes photosynthesis, not cellular respiration. Cellular respiration breaks down glucose rather than producing it.
4. Step 4: Evaluate the third statement: 'Cellular respiration converts glucose and oxygen into carbon dioxide, water, and ATP.' This is correct because it accurately describes the process of cellular respiration, which involves the breakdown of glucose in the presence of oxygen to produce ATP, carbon dioxide, and water.
5. Step 5: Evaluate the fourth statement: 'Cellular respiration takes place exclusively in the cytoplasm of eukaryotic cells.' This is incorrect because cellular respiration occurs in multiple locations within eukaryotic cells, including the cytoplasm (glycolysis) and mitochondria (Krebs cycle and electron transport chain).
