, BIO 171 FINAL EXAM — CELL BIOLOGY, MICROBIOLOGY,
Questions 1 – 52
MICROSCOPY & INFECTIOUS DISEASE
1. Which organelle contains genomic content (DNA)?
A. Endoplasmic Reticulum
B. Lysosomes
C. Nucleus
D. Ribosomes
CORRECT ANSWER C — Nucleus
RATIONALE Per the source material, the nucleus contains the genomic content (DNA) of the
cell. The endoplasmic reticulum (option A) is a series of membrane-enclosed sacs.
Lysosomes (option B) contain hydrolytic enzymes. Ribosomes (option D) function
in protein synthesis.
2. The endoplasmic reticulum is best described as:
A. A series of membrane-enclosed sacs and interconnected tubes
B. The site of ATP production
C. The control center of the cell
D. The site of photosynthesis
CORRECT ANSWER A — A series of membrane-enclosed sacs and interconnected tubes
RATIONALE Per the source material, the endoplasmic reticulum is a series of membrane-
enclosed sacs and interconnected tubes. The rough ER is studded with ribosomes
and involved in protein synthesis and transport; the smooth ER is involved in lipid
synthesis and detoxification.
, 3. Lysosomes function to:
A. Contain hydrolytic enzymes for digestion
B. Synthesize proteins
C. Produce ATP through oxidative phosphorylation
D. Store genomic DNA
CORRECT ANSWER A — Contain hydrolytic enzymes for digestion
RATIONALE Per the source material, lysosomes contain hydrolytic enzymes that digest
macromolecules, old organelles, and foreign material. They function as the cell's
digestive system. Protein synthesis (option B) occurs on ribosomes. ATP
production (option C) occurs in mitochondria.
4. Chloroplasts are the site of:
A. Protein synthesis
B. Cellular respiration
C. Photosynthesis
D. Lipid synthesis
CORRECT ANSWER C — Photosynthesis
RATIONALE Per the source material, chloroplasts are the site of photosynthesis — the process
by which light energy is converted to chemical energy in the form of glucose.
Protein synthesis (option A) occurs on ribosomes. Cellular respiration (option B)
occurs in mitochondria.
