Questions & Verified Answers
1. Which of the following components is the primary structural element of the plasma
membrane?
A. Proteins
B. Nucleic acids
C. Phospholipids
D. Carbohydrates
Answer: C
Rationale: Phospholipids form the fundamental bilayer structure of the plasma membrane, providing a barrier
that is selectively permeable. Exam questions often test the ability to distinguish this concept from closely
related distractors, making a clear rationale essential for mastery. Applying this knowledge in clinical settings
supports safe, evidence-based practice and improves patient outcomes.
2. The ‘powerhouse’ of the cell responsible for generating ATP through cellular respiration is
the:
A. Nucleus
B. Ribosome
C. Lysosome
D. Mitochondrion
Answer: D
Rationale: Mitochondria are the organelles where the final stages of cellular respiration occur, producing the
majority of the cell’s ATP. Exam questions often test the ability to distinguish this concept from closely related
distractors, making a clear rationale essential for mastery. Applying this knowledge in clinical settings supports
safe, evidence-based practice and improves patient outcomes.
3. Which organelle is primarily responsible for the synthesis of proteins?
A. Golgi apparatus
B. Ribosome
C. Smooth ER
D. Vacuole
Answer: B
Rationale: Ribosomes are the site of protein synthesis, translating genetic instructions into polypeptide chains.
This is an important clinical concept because selecting the correct answer (B) requires understanding both the
pathophysiology and the practical nursing implications. Recognizing this principle allows the nurse to prioritize
care, anticipate complications, and provide accurate patient education.

4. What is the primary function of the Golgi apparatus?
A. Energy production
B. Lipid synthesis
C. DNA replication
D. Modifying, sorting, and packaging proteins
Answer: D
Rationale: The Golgi apparatus acts as a shipping and receiving center, processing proteins received from the
ER before sending them to their destinations. This is an important clinical concept because selecting the
correct answer (D) requires understanding both the pathophysiology and the practical nursing implications.
Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide accurate
patient education.
5. Which type of transport requires the expenditure of energy (ATP) to move substances
against their concentration gradient?
A. Simple diffusion
B. Active transport
C. Osmosis
D. Facilitated diffusion
Answer: B
Rationale: Active transport moves molecules from low to high concentration, which requires energy input from
the cell. Exam questions often test the ability to distinguish this concept from closely related distractors, making
a clear rationale essential for mastery. Applying this knowledge in clinical settings supports safe,
evidence-based practice and improves patient outcomes.
6. The diffusion of water across a selectively permeable membrane is known as:
A. Endocytosis
B. Osmosis
C. Phagocytosis
D. Exocytosis
Answer: B
Rationale: Osmosis is the specific term for the passive movement of water molecules through a membrane.
This is an important clinical concept because selecting the correct answer (B) requires understanding both the
pathophysiology and the practical nursing implications. Recognizing this principle allows the nurse to prioritize
care, anticipate complications, and provide accurate patient education.
