Which of the following cell organelles is responsible for extracting energy from carbohydrates to form ATP?
Answer: (D) Mitochondrion. Answer: (D) Mitochondrion Solution: Mitochondria are the sites of aerobic respiration where energy from carbohydrates is released and stored as ATP, earning them the name 'power houses' of the cell.
- A.Lysosome
- B.Ribosome
- C.Chloroplast
- D.Mitochondrion✓
Correct Answer
(D) Mitochondrion
Solution & Explanation
Answer: (D) Mitochondrion Solution: Mitochondria are the sites of aerobic respiration where energy from carbohydrates is released and stored as ATP, earning them the name 'power houses' of the cell. Lysosomes carry out intracellular digestion, ribosomes synthesise proteins, and chloroplasts capture light energy for photosynthesis — none of these is the chief ATP-producing organelle from carbohydrate oxidation. NCERT Reference: Ch 8, p.97, lines 11–13: "Mitochondria are the sites of aerobic respiration. They produce cellular energy in the form of ATP, hence they are called ‘power houses’ of the cell."
