Multiple choice
1. Which statement best describes the cellular function of metabolic absorption?
a. Cells can produce proteins. C. Cells can take in and use nutrients.
b. Cells can secrete digestive enzymes. D. Cells can synthesize fats.
Right answer: c
In metabolic absorption, all cells take in and use nutrients and other substances
from theirsurroundings. The remaining options are not inclusive in their
descriptions of cellular metabolic absorption.
Pts: 1 ref: page 2
2. Most of a cell’s genetic information, including rna and dna, is contained in the:
a. Mitochondria c. Nucleolus
b. Ribosome d. Lysosome
Right answer: 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 other options do not contain most of a cell’s genetic
information.

3. Which component of the cell p ro dnuuc erss ihnygd trobg. ce on m
peroxide (h2o2) by using
oxygen to remove hydrogen atoms from specific substrates in an oxidative
reaction?
a. Lysosomes c. Ribosomes
b. Peroxisomes d. Oxyhydrosomes
Right answer: b
Peroxisomes are so named because they usually contain enzymes that use oxygen to
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. Oxyhydrosomesare involved in enzyme
production.
Pts: 1 ref: page 8
4. Which cell component is capable of cellular autodigestion when it is released
during cellinjury?
a. Ribosome c. Smooth endoplasmic reticulum
b. Golgi complex d. Lysosomes
The lysosomal membrane acts as a protective shield between the powerful digestive
enzymes within the lysosome and the cytoplasm, preventing their leakage into the
cytoplasmic matrix. Disruption of the membrane by various treatments or cellular
injury leads to a release of the lysosomal enzymes, which can then react with their
specific substrates, causing cellular self-digestion. The other options do not correctly
describe thisprocess.
