Cell Organelles (ER, Golgi, Lysosomes, Mitochondria, Plastids, Vacuoles)Quiz - Solve & Score
Q1. A sprinter's thigh muscles burn glucose furiously during a 100 m dash and demand a steady flood of usable energy; which organelle releases that energy as ATP?
- A.Golgi apparatus
- B.Lysosome
- C.Ribosome
- D.Mitochondrion
Answer: D. Mitochondrion
Cellular respiration that converts glucose energy into ATP happens in the mitochondrion, so the muscle's energy supply comes from mitochondria.
Q2. A textbook calls one organelle the 'powerhouse of the cell' because it churns out the molecule cells spend as fuel; what is that fuel molecule?
- A.ATP
- B.Glucose
- C.Chlorophyll
- D.DNA
Answer: A. ATP
Mitochondria release energy by oxidising glucose and store it as ATP, the cell's spendable energy currency.
Q3. A heart-muscle cell never rests and so contains thousands of mitochondria, while a barely active skin cell has far fewer; what does this difference in mitochondrial number reveal?
- A.Mitochondria multiply only in skin cells
- B.Heart cells use mitochondria for storage, not energy
- C.Cells with higher energy demand carry more mitochondria
- D.Larger cells always have fewer mitochondria
Answer: C. Cells with higher energy demand carry more mitochondria
Mitochondria supply ATP, so tissues that work constantly, like cardiac muscle, hold many more mitochondria than low-energy tissues such as resting skin.
