SECTION 1: CELLULAR BIOLOGY & ORGANELLE FUNCTION
--- --- --- --- --- --- ---
(Questions 1–30) --- ---
Question 1: Which organelle is responsible for cellular
--- --- --- --- --- --- --- ---
respiration and energy production (ATP) in eukaryotic cells?
--- --- --- --- --- --- --- ---
• A) Ribosome
--- ---
• B) Golgi apparatus
--- --- ---
• C) Mitochondria
--- ---
• D) Endoplasmic reticulum
--- --- ---
,Answer: C --- ---
Rationale: Mitochondria are the primary sites of ATP production
--- --- --- --- --- --- --- --- ---
through aerobic respiration. They contain the electron transport
--- --- --- --- --- --- --- ---
chain and ATP synthase complexes, making them the
--- --- --- --- --- --- --- ---
"powerhouses" of the cell. --- --- --- ---
---
Question 2: Which organelle provides sites for cellular protein
--- --- --- --- --- --- --- --- ---
synthesis? ---
• A) Lysosomes
--- ---
• B) Ribosomes
--- ---
• C) Nucleus
--- ---
• D) Peroxisomes
--- ---
Answer: B --- ---
Rationale: Ribosomes are the sites of protein synthesis in the cell.
--- --- --- --- --- --- --- --- --- --- ---
They may be free in the cytoplasm or attached to rough
--- --- --- --- --- --- --- --- --- --- ---
endoplasmic reticulum, translating mRNA sequences into
--- --- --- --- --- ---
polypeptide chains. --- ---
---

Question 3: Which organelle is the largest membrane-bound
--- --- --- --- --- --- --- ---
organelle, usually found in the cell center, and is responsible for
--- --- --- --- --- --- --- --- --- --- ---
cell division and control of genetic information?
--- --- --- --- --- --- ---
• A) Nucleolus
--- ---
B) Ribosome
--- ---
• C) Nucleus
--- ---
• D) Endoplasmic reticulum
--- --- ---
Answer: C --- ---
Rationale: The nucleus is the largest membrane-bound organelle
--- --- --- --- --- --- --- ---
and contains the cell's genetic material (DNA). Its primary
--- --- --- --- --- --- --- --- ---
functions include cell division and the control of genetic
--- --- --- --- --- --- --- --- ---
information. ---
---
Question 4: Which small, dense structure composed largely of
--- --- --- --- --- --- --- --- ---
RNA and proteins is found within the nucleus?
--- --- --- --- --- --- --- ---
• A) Mitochondrion
--- ---
• B) Peroxisome
--- ---
• C) Nucleolus
--- ---
• D) Lysosome
--- ---
, Answer: C --- ---
Rationale: The nucleolus is a small, dense structure within the
--- --- --- --- --- --- --- --- --- ---
nucleus composed largely of RNA and proteins. It is the site of
--- --- --- --- --- --- --- --- --- --- --- ---
ribosomal RNA synthesis and ribosome assembly.
--- --- --- --- --- ---
---
Question 5: Which saclike structures originate from the Golgi
--- --- --- --- --- --- --- --- ---
complex and contain digestive enzymes?
--- --- --- --- ---
• A) Peroxisomes
--- ---
• B) Lysosomes
--- ---
• C) Ribosomes
--- ---
• D) Cytosol
--- ---
Answer: B --- ---
Rationale: Lysosomes are membrane-bound organelles
--- --- --- --- ---
containing digestive (hydrolytic) enzymes. They originate from
--- --- --- --- --- --- ---
the Golgi complex and function in intracellular digestion,
--- --- --- --- --- --- --- ---
recycling cellular components, and destroying pathogens.
