,📝 Chapter 1: Cellular Function
1. Which of the following is the primary function of the endoplasmic
reticulum (ER) in the cell?

A) Synthesis of proteins
B) Cellular respiration
C) Lipid metabolism
D) DNA replication

✅ Correct Answer: A) Synthesis of proteins
💡Rationale: The rough endoplasmic reticulum (ER) is primarily
responsible for synthesizing proteins, while the smooth ER is involved in
lipid metabolism and detoxification. Cellular respiration takes place in the
mitochondria, and DNA replication occurs in the nucleus.



2. What role do lysosomes play in cellular function?

A) Synthesize proteins
B) Provide structural support
C) Break down cellular waste and debris
D) Produce energy in the form of ATP

✅ Correct Answer: C) Break down cellular waste and debris
💡Rationale: Lysosomes are membrane-bound organelles that contain
enzymes responsible for digesting and breaking down waste materials,
cellular debris, and foreign particles. They are vital for maintaining cellular
cleanliness.



3. Which of the following best describes the function of the
mitochondria?


3

, A) Protein synthesis
B) Storage of calcium ions
C) ATP production through oxidative phosphorylation
D) Packaging and transport of proteins

✅ Correct Answer: C) ATP production through oxidative
phosphorylation
💡Rationale: Mitochondria are known as the powerhouse of the cell due to
their role in producing ATP through oxidative phosphorylation. They are
crucial for energy production. Protein synthesis occurs in ribosomes, while
calcium storage is in the endoplasmic reticulum.



4. The process of cellular apoptosis is best described as which of the
following?

A) A programmed cell death process
B) A form of cellular growth
C) The active transport of ions across the membrane
D) The breakdown of glucose for energy production

✅ Correct Answer: A) A programmed cell death process
💡Rationale: Apoptosis is a controlled, programmed process of cell death
that allows the body to remove damaged or unneeded cells without causing
inflammation or harm to surrounding tissues.



5. Which cellular component is responsible for the synthesis of ribosomal
RNA (rRNA)?

A) Nucleus
B) Ribosome
C) Endoplasmic reticulum
D) Nucleolus
