MULTIPLE CHOICE
1. Which statement best describes the cellular function of metabolic absorption?
a. Cells can produce proteins.
b. Cells can secrete digestive enzymes.
c. Cells can take in and use nutrients.
d. Cells can synthesize fats.
ANS: C
In metabolic absorption, all cells take in and use nutrients and other substances from their
surroundings. The remaining options are not inclusive in their descriptions of cellular metabolic
absorption.
PTS: 1 DIF: Cognitive Level: Remembering
2. Where is most of a cell’s genetic information, including RNA and DNA, contained?
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Lysosome
ANS: C
The nucleus contains the nucleolus, a small dense structure composed largely of RNA, most of
the cellular DNA, and the DNA-binding proteins, such as the histones, which regulate its
activity. The mitochondria are responsible for cellular respiration and energy production.
Ribosomes’ chief function is to provide sites for cellular protein synthesis. Lysosomes function
as the intracellular digestive system.
PTS: 1 DIF: Cognitive Level: Remembering
3. Which component of the cell produces hydrogen peroxide (H2O2) by using oxygen to remove
hydrogen atoms from specific substrates in an oxidative reaction?
a. Lysosomes
b. Peroxisomes
c. Ribosomes
d. Endosome
ANS: B
