## Unit 1: Cellular Biology & Function
### Question 1
**What is the primary function of the cell membrane?**
- A) Protein synthesis
- B) Energy production through oxidative phosphorylation
- C) Selective permeability and protection
- D) Genetic information storage
**Correct Answer: C**
**Rationale:** The cell membrane (plasma membrane) provides selective permeability, allowing
certain substances to enter or leave the cell while maintaining the intracellular environment. It
also provides protection and structural support. Protein synthesis occurs at ribosomes (A).
Energy production occurs in mitochondria (B). Genetic information is stored in the nucleus (D).

### Question 2
**Which organelle is responsible for ATP production through oxidative phosphorylation?**
- A) Ribosome
- B) Golgi apparatus
- C) Mitochondrion
- D) Smooth endoplasmic reticulum
,Page 3 of 191
**Correct Answer: C**
**Rationale:** Mitochondria are the powerhouses of the cell, responsible for ATP production
through oxidative phosphorylation. Ribosomes (A) synthesize proteins. The Golgi apparatus (B)
modifies and packages proteins. The smooth endoplasmic reticulum (D) is involved in lipid
synthesis and detoxification.
---
### Question 3
**Which cellular organelle is responsible for the synthesis of proteins destined for secretion?**
- A) Smooth endoplasmic reticulum
- B) Rough endoplasmic reticulum
- C) Golgi apparatus
- D) Lysosome
**Correct Answer: B**
**Rationale:** The rough endoplasmic reticulum contains ribosomes, which are the sites of
protein synthesis. Proteins destined for secretion are synthesized on the rough ER, then
transported to the Golgi apparatus for modification and packaging. The smooth ER (A)
synthesizes lipids. The Golgi apparatus (C) modifies proteins but does not synthesize them.
Lysosomes (D) are involved in intracellular digestion.

### Question 4
**A patient with a genetic defect in mitochondrial DNA would most likely experience
dysfunction in which cellular process?**
- A) Protein synthesis
, Page 4 of 191
- B) Lipid metabolism
- C) ATP production
- D) DNA replication
**Correct Answer: C**
**Rationale:** Mitochondria contain their own DNA (mtDNA) that encodes proteins essential
for oxidative phosphorylation and ATP production. Defects in mtDNA primarily affect energy
production, particularly in tissues with high energy demands (muscle, brain). Protein synthesis
(A) occurs primarily in the cytoplasm. Lipid metabolism (B) occurs in the smooth ER and
cytoplasm. DNA replication (D) occurs in the nucleus.
---
### Question 5
**The Golgi apparatus is primarily responsible for which cellular function?**
- A) Synthesizing ribosomal RNA
- B) Modifying, sorting, and packaging proteins
- C) Producing ATP
- D) Degrading cellular waste
**Correct Answer: B**
**Rationale:** The Golgi apparatus modifies, sorts, and packages proteins and lipids for
secretion or delivery to other organelles. The nucleolus synthesizes ribosomal RNA (A).
Mitochondria produce ATP (C). Lysosomes degrade cellular waste (D).
