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 substancesfrom
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 cellularrespiration 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
Peroxisomes are so named because they usually contain enzymes that use oxygento
remove hydrogen atoms from specific substrates in an oxidative reaction that produces
H2O2, which is a powerful oxidant and potentially destructive if it accumulates or
escapes from peroxisomes.
Ribosomes are RNA-protein complexes (nucleoproteins) that are synthesized in the
nucleolus and secreted into the cytoplasm through pores in the nuclear envelope called
nuclear pore complexes. Lysosomes are saclike structures that originate from the Golgi
complex and contain more than 40 digestive enzymes called hydrolases, which catalyze
bonds in proteins, lipids, nucleic acids, and carbohydrates. An endosome is a vesical
that has been pinched off from the cellular membrane.
