Question 1
Which organelle is primarily responsible for producing ATP
during cellular respiration?
A. Ribosome
B. Golgi apparatus
C. Mitochondrion
D. Lysosome
Answer: C. Mitochondrion
Rationale: The mitochondrion is the site of cellular respiration
and ATP production in eukaryotic cells.

performing all life functions.
Question 3
Which macromolecule stores genetic information?
A. Lipids
B. Proteins
C. Carbohydrates
D. Nucleic acids
Answer: D. Nucleic acids
Rationale: DNA and RNA are nucleic acids that store and
transmit genetic information.
Question 4
During photosynthesis, plants convert:
