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.
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.

2. Most of a cell’s genetic information, including RNA and DNA,
is contained in the:
a. Mitochondria c. Nucleolus
b. Ribosome 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 other options do not contain most of a cell’s
genetic information.

3. Which component of the cell
prodNuUceRsSIhNyGdTroBg.CenOMperoxide (H2O2) by using
oxygen to remove hydrogen atoms from specific
substrates in an oxidative reaction?
a. Lysosomes c. Ribosomes
b. Peroxisomes d. Oxyhydrosomes
ANS: 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. Oxyhydrosomes are
involved in enzyme production.

4. Which cell component is capable of cellular autodigestion
when it is released during cell injury?
a. Ribosome c. Smooth endoplasmic
reticulum
b. Golgi complex d. Lysosomes
ANS: D
, 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 this process.
PTS: 1 REF: Pages 7-8
5. What is the sequence of steps in the development of a
digestive enzyme by the pancreas cells from the initial
transcription to the release from the cell?
a. The enzyme is transcribed from DNA by RNA in the
nucleus, proceeds to the ribosome for synthesis, and
is transported in a secretory vesicle to the cell
membrane.
b. The enzyme is transcribed from RNA by DNA in the
nucleus, proceeds to the lysosome for synthesis, and is
transported in an encapsulated membrane to the cell
membrane.
c. The enzyme is transcribed by the mitochondria in the
nucleus, proceeds to the ribosome for synthesis, and is
transported in a cytoskeleton to the cell membrane.
d. The enzyme is transcribed from DNA by RNA in the
nucleus, proceeds to the Golgi complex for synthesis,
and is transported in a cytosol to the cell membrane.
ANS: A
The enzyme is transcribed from DNA by RNA in the
nucleus, proceeds to the ribosome for synthesis, and is
transported in a secretory vesicle to the cell membrane.
The other options do not correctly describe this process.

6. During which phase of the cell cycle is DNA synthesized?
a. G1 c. G2
b. S d. M
ANS: B
