ANATOMY & CELL BIOLOGY (HOMEOSTASIS, CELLS, TRANSPORT,
METABOLISM)
Q1. A patient’s cells are placed in a hypertonic solution during a lab demonstration.
What cellular response is most likely to occur?
A. Cells swell due to water influx
B. Cells remain unchanged
C. Cells shrink due to water efflux
D. Cells divide rapidly
Correct Answer: 🔴 C. Cells shrink due to water efflux
Explanation: 🔹 In a hypertonic solution, solute concentration is higher outside the cell,
causing water to move out via osmosis. This leads to cell shrinkage (crenation in animal
,cells). Options A and D are incorrect because water does not move into the cell in
hypertonic conditions, and cell division is unrelated to osmotic balance.
Q2. Which organelle is primarily responsible for ATP production in eukaryotic cells?
A. Ribosome
B. Mitochondria
C. Golgi apparatus
D. Lysosome
Correct Answer: 🔴 B. Mitochondria
Explanation: 🔹 Mitochondria generate ATP through aerobic respiration. Ribosomes
synthesize proteins, Golgi modifies proteins, and lysosomes digest waste materials.
Q3. What type of transport requires energy to move substances against their
concentration gradient?
A. Passive diffusion
B. Osmosis
C. Facilitated diffusion
D. Active transport
Correct Answer: 🔴 D. Active transport
Explanation: 🔹 Active transport uses ATP to move molecules against a gradient. Passive
diffusion, osmosis, and facilitated diffusion all move substances down a gradient without
energy.
Q4. Which macromolecule is the primary structural component of cell membranes?
A. Carbohydrates
B. Lipids (phospholipids)
C. Proteins
D. Nucleic acids
Correct Answer: 🔴 B. Lipids (phospholipids)
,Explanation: 🔹 Phospholipids form the bilayer of cell membranes, creating a
hydrophobic barrier. Proteins assist in transport and signaling but are not the main
structural component.
Q5. A mutation prevents ribosomes from functioning properly. Which process is
most directly affected?
A. DNA replication
B. Protein synthesis
C. Lipid metabolism
D. Cellular respiration
Correct Answer: 🔴 B. Protein synthesis
Explanation: 🔹 Ribosomes are responsible for translating mRNA into proteins. Without
functional ribosomes, protein synthesis stops, affecting all cellular functions.
Q6. Which phase of the cell cycle is characterized by DNA replication?
A. G1 phase
B. S phase
C. G2 phase
D. M phase
Correct Answer: 🔴 B. S phase
Explanation: 🔹 DNA replication occurs in the S (synthesis) phase, ensuring each
daughter cell receives identical genetic material.
Q7. What is the primary function of lysosomes?
A. Energy production
B. Protein synthesis
C. Intracellular digestion
D. Lipid storage
Correct Answer: 🔴 C. Intracellular digestion
, Explanation: 🔹 Lysosomes contain enzymes that break down waste, pathogens, and
cellular debris.
Q8. Which transport mechanism involves vesicle formation to bring large particles
into the cell?
A. Exocytosis
B. Endocytosis
C. Diffusion
D. Osmosis
Correct Answer: 🔴 B. Endocytosis
Explanation: 🔹 Endocytosis brings large molecules into cells via vesicles. Exocytosis
removes materials from the cell.
Q9. The sodium-potassium pump moves how many ions per cycle?
A. 1 Na⁺ out, 1 K⁺ in
B. 2 Na⁺ in, 2 K⁺ out
C. 3 Na⁺ out, 2 K⁺ in
D. 3 K⁺ out, 2 Na⁺ in
Correct Answer: 🔴 C. 3 Na⁺ out, 2 K⁺ in
Explanation: 🔹 This pump maintains membrane potential by actively transporting 3
sodium ions out and 2 potassium ions into the cell.
Q10. Which biomolecule stores genetic information?
A. Proteins
B. Lipids
C. Carbohydrates
D. Nucleic acids
Correct Answer: 🔴 D. Nucleic acids
