NSG 5003 Week 1 QUIZ
1. It is true that a eukaryotic cell:
A. Is smaller than a prokaryotic cell.
B. Contains structures called organelles.
C. Lacks a well-defined nucleus.
D. Does not contain histones.
Rationale
Eukaryotic cells contain organelles and histones, they have a well-defined nucleus, and are larger
than prokaryotic cells.
2. The function of a histone found in a eukaryote cell focuses on cellular:
A. Division
B. Movement
C. Activities
D. Deoxyribonucleic acid (DNA) folding
Rationale
The histones are binding proteins that cause the supercoiling of DNA into chromosomes and do
not affect cellular division, movement, or activities.
3. An organelle that is responsible for the metabolism of cellular energy is referred to as a/an:
A. Golgi complex
B. Mitochondrio
n
C. Endoplasmic reticulum
, D. Nucleolus
Rationale
Mitochondria play a role in cellular metabolism, cellular respiration, and energy production. The
Golgi complex is responsible for processing and packaging proteins from the endoplasmic
reticulum, where they are synthesized. The nucleolus is a small, dense structure that contains the
ribonucleic acid (RNA), DNA, and DNA-binding proteins.
4. Which statement best describes a desmosome?
A. A desmosome is a barrier to diffusion.
B. Desmosomes hold cells together by continuous bands.
C. A desmosome is a communicating tunnel.
D. Desmosomes function as a zona occludens.
Rationale
The desmosome is a type of cell junction. The other two types include tight junctions and gap
junctions. Desmosomes hold cells together by forming a continuous band of epithelial tissue or
belt (or button like) points of contact. They are also a source of structural stability. Tight
junctions serve as barriers to diffusion and prevent the movement of substances through transport
proteins. Gap junctions are clusters of communicating tunnels.
5. Which statement describes the function of a second messenger?
A. Extracellular ligand that binds with membrane-bound receptors
B. Intracellular enzyme that once will trigger a cascade of intracellular events
C. Chemical messenger that opens specific channels in the cell membrane
D. Chemical messenger that blocks a membrane-bound receptor signal
Rationale
The binding of a ligand to a cell surface receptor triggers the activation of intracellular second
