Chapter 1: Cellular Biology
Multiple Choice Questions with Answers & Rationales
1. Which statement best describes the cellular function of metabolic absorption?
a. Cells produce proteins
b. Cells secrete digestive enzymes
c. Cells take in and utilize nutrients
d. Cells synthesize fats
Answer: C
Rationale: Metabolic absorption refers to the ability of cells to take in nutrients and other
substances from their environment and use them for cellular processes. The other options
describe different cellular functions such as synthesis or secretion.
2. Most of a cell’s genetic material (DNA and RNA) is located in the:
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Lysosome
Answer: C
Rationale: The nucleolus, found within the nucleus, contains RNA and is associated with
most of the cell’s genetic material and protein synthesis regulation. Other organelles do not
store the majority of DNA.
3. Which organelle generates hydrogen peroxide (H₂O₂) during oxidative reactions?
a. Lysosomes
b. Peroxisomes
c. Ribosomes
d. Oxyhydrosomes
Answer: B
Rationale: Peroxisomes contain oxidative enzymes that use oxygen to remove hydrogen
atoms, producing hydrogen peroxide as a byproduct.
4. Which cellular structure can cause self-digestion if released during injury?
a. Ribosome
b. Smooth endoplasmic reticulum
c. Golgi complex
d. Lysosomes

(Pathophysiologyhttps://www.stuvia.com/user/docstudent96
9th Edition McCance – Test https://www.stuvia.com/user/docstudent96
Bank:Q&A).
Answer: D
Rationale: Lysosomes contain powerful digestive enzymes. If their membrane is disrupted,
these enzymes are released into the cytoplasm, leading to autodigestion of the cell.
5. What is the correct sequence for enzyme production and secretion?
a. DNA → RNA (nucleus) → ribosome → vesicle → membrane
b. RNA → DNA → lysosome → membrane
c. Mitochondria → ribosome → cytoskeleton
d. DNA → Golgi → cytosol
Answer: A
Rationale: Protein synthesis begins with transcription of DNA to RNA in the nucleus,
followed by translation in ribosomes. The protein is then transported via vesicles to the cell
membrane for secretion.
6. During which phase of the cell cycle is DNA synthesized?
a. G1
b. S
c. G2
d. M
Answer: B
Rationale: DNA replication occurs during the S (synthesis) phase, preparing the cell for
division.
7. Which organic compound functions as receptors, channels, and enzymes?
a. Lipids
b. Proteases
c. Proteins
d. Carbohydrates
Answer: C
Rationale: Proteins play multiple roles including acting as receptors, forming channels for
ions, and functioning as enzymes.
8. Proteolytic cascades are important in managing which diseases?
a. Cardiac disorders
b. Autoimmune and malignant diseases
c. GI disorders
d. Endocrine disorders
Answer: B
Rationale: Abnormal protease activity is linked to cancer and autoimmune diseases, making
these pathways important therapeutic targets.
9. What prevents water-soluble molecules from crossing the cell membrane?
a. Carbohydrates
b. Channel proteins

Bank:Q&A).
c. Glycoproteins
d. Lipid bilayer
Answer: D
Rationale: The lipid bilayer is hydrophobic, which prevents water-soluble (hydrophilic)
molecules from passing through easily.
10. The fluid mosaic model explains:
a. Cell membrane structure and function
b. Body solidity
c. Tissue differentiation
d. Fluid movement
Answer: A
Rationale: The fluid mosaic model describes the flexible and dynamic nature of the cell
membrane composed of lipids and proteins.
11. Which communication occurs through direct contact between cells?
a. Gap junctions
b. Receptors
c. Hormones
d. Ligands
Answer: A
Rationale: Gap junctions allow direct passage of ions and molecules between adjacent
cells.
12. Which signaling method uses the bloodstream?
a. Paracrine
b. Autocrine
c. Neurotransmitter
d. Hormonal
Answer: D
Rationale: Hormones are transported via the bloodstream to act on distant target cells.
13. Which signaling uses local mediators?
a. Paracrine
b. Autocrine
c. Neurotransmitter
d. Hormonal
Answer: A
Rationale: Paracrine signaling affects nearby cells and is short-lived.
14. Neurotransmitters bind to:
a. Lipids
b. Ribosomes
