1. Which organelle is the site of ATP production?
A. Ribosome
B. Mitochondria
C. Golgi apparatus
D. Lysosome
Correct Answer: B
Rationale: Mitochondria generate ATP through cellular respiration.
2. Which organelle assembles proteins for secretion?
A. Free ribosome
B. Rough ER
C. Lysosome
D. Smooth ER
,Correct Answer: B
Rationale: Ribosomes on rough ER synthesize proteins destined for
export.
3. Which process moves water across a membrane?
A. Active transport
B. Diffusion
C. Osmosis
D. Endocytosis
Correct Answer: C
Rationale: Osmosis is the passive movement of water through a
selectively permeable membrane.
4. Which macromolecule stores genetic information?
A. Protein
B. Lipid
C. Nucleic acid
D. Carbohydrate
Correct Answer: C
Rationale: DNA and RNA are nucleic acids that store and transmit
hereditary information.
5. Which organelle detoxifies chemicals and synthesizes lipids?
,A. Rough ER
B. Smooth ER
C. Golgi apparatus
D. Lysosome
Correct Answer: B
Rationale: Smooth ER metabolizes toxins and produces lipids.
6. Which organelle contains digestive enzymes?
A. Ribosome
B. Lysosome
C. Golgi apparatus
D. Smooth ER
Correct Answer: B
Rationale: Lysosomes digest waste and damaged organelles.
7. Which solution causes a cell to swell?
A. Hypertonic
B. Hypotonic
C. Isotonic
D. Neutral
Correct Answer: B
Rationale: Water enters the cell in a hypotonic solution.
8. Which organelle modifies and packages proteins for delivery?
, A. Ribosome
B. Golgi apparatus
C. Lysosome
D. Smooth ER
Correct Answer: B
Rationale: Golgi apparatus sorts and directs proteins to their proper
locations.
9. Active transport differs from diffusion because it:
A. Moves water only
B. Requires energy
C. Moves substances down their gradient
D. Occurs passively
Correct Answer: B
Rationale: Active transport uses ATP to move molecules against a
concentration gradient.
10. Facilitated diffusion requires:
A. ATP
B. Transport proteins
C. Vesicles
D. Active energy
