MODULE 1: CELLULAR BIOLOGY, INJURY, ADAPTATION, AND GENETICS
TOPIC 1.1: CELLULAR STRUCTURE & FUNCTION
Questions 1-20
Q1. Which organelle is responsible for generating adenosine triphosphate (ATP)
through oxidative phosphorylation?
A) Ribosome
B) Golgi apparatus
C) Mitochondrion
D) Endoplasmic reticulum
Answer: C
Rationale: Mitochondria are the "powerhouses" of the cell, responsible for ATP
production through oxidative phosphorylation in the electron transport chain.
Ribosomes synthesize proteins; the Golgi apparatus modifies and packages
proteins; the endoplasmic reticulum synthesizes lipids and proteins.

,Q2. Which cellular structure regulates the passage of substances into and out
of the cell?
A) Nucleus
B) Cell membrane
C) Cytoplasm
D) Peroxisome
Answer: B
Rationale: The cell membrane (plasma membrane) is selectively permeable and
regulates the movement of substances into and out of the cell. The nucleus
contains genetic material; the cytoplasm is the fluid-filled space; peroxisomes
contain oxidative enzymes.
Q3. Which type of RNA is responsible for carrying the genetic code from DNA to
the ribosome?
A) Messenger RNA (mRNA)
B) Transfer RNA (tRNA)
C) Ribosomal RNA (rRNA)
D) Small nuclear RNA (snRNA)
Answer: A
Rationale: mRNA carries the genetic code from DNA in the nucleus to the
ribosome, where protein synthesis occurs. tRNA brings amino acids to the
ribosome; rRNA is a structural component of ribosomes; snRNA is involved in RNA
splicing.
Q4. What is the function of the Golgi apparatus?
A) ATP production
B) Protein synthesis
3
, C) Modifying, sorting, and packaging proteins
D) Intracellular digestion
Answer: C
Rationale: The Golgi apparatus modifies, sorts, and packages proteins and lipids
into vesicles for transport within the cell or secretion. Mitochondria produce
ATP; ribosomes synthesize proteins; lysosomes perform intracellular digestion.
Q5. Which cellular organelle contains hydrolytic enzymes for intracellular
digestion?
A) Peroxisome
B) Lysosome
C) Ribosome
D) Nucleus
Answer: B
Rationale: Lysosomes are membrane-bound organelles containing hydrolytic
enzymes
that digest cellular waste, foreign materials, and damaged organelles.
Peroxisomes contain oxidative enzymes; ribosomes synthesize proteins; the
nucleus contains genetic material.
Q6. The Na+/K+ ATPase pump maintains the resting membrane potential by:
A) Pumping sodium into the cell and potassium out of the cell
B) Pumping sodium out of the cell and potassium into the cell
C) Pumping both sodium and potassium into the cell
D) Pumping both sodium and potassium out of the cell
Answer: B
Rationale: The Na+/K+ ATPase pump actively transports 3 sodium ions out of the
cell and 2 potassium ions into the cell, maintaining the concentration
