CHAPTER 1: CELLULAR BIOLOGY LL LL LL

1. Which statement best describes the cellular function of metabolic absorption?
ll ll ll ll ll ll ll ll ll
a. Cells can produce proteins. llc. Cells can take in and use nutrients.
ll ll ll ll ll ll ll ll
b. Cells can secrete digestive enzymes. lld. Cells can synthesize fats.
ll ll ll l l ll ll ll
ANS: C ll
In metabolic absorption, all cells take in and use nutrients and other substances from
ll ll ll ll ll ll ll ll ll ll ll ll ll
theirsurroundings. The remaining options are not inclusive in their descriptions of
ll l ll ll ll ll ll ll ll ll ll ll
cellular metabolic absorption.

2. Most of a cell’s genetic information, including RNA and DNA, is contained in the:
ll ll ll ll ll ll ll ll ll ll ll ll ll
a. Mitochondria c. Nucleolus
b. Ribosome d. Lysosome ll ll l l
ANS: C ll
The nucleus contains the nucleolus, a small dense structure composed largely of RNA,
ll ll ll ll ll ll ll ll ll ll ll ll
most of the cellular DNA, and the DNA-binding proteins, such as the histones, which
ll ll ll ll ll ll ll ll ll ll ll ll ll ll
regulate its activity. The other options do not contain most of a cell’s genetic
ll ll ll ll ll ll ll ll ll ll ll ll ll ll
information.

3. Which component of the cell prodNuU

peroxide (H2O2) by using oxygen to
ll ll ll ll ll ll ll ll ll
remove hydrogen atoms from specific substrates in an oxidative reaction?
ll ll ll ll ll ll ll ll ll ll
a. Lysosomes c. Ribosomes
b. Peroxisomes d. Oxyhydrosomes l l
ANS: B ll
Peroxisomes are so named because they usually contain enzymes that use oxygen to
ll ll ll ll ll ll ll ll ll ll ll ll
remove hydrogen atoms from specific substrates in an oxidative reaction that produces
ll ll ll ll ll ll ll ll ll ll ll ll

ll H2O2, which is a powerful oxidant and potentially destructive if it accumulates or escapes
ll ll ll ll ll ll ll ll ll ll ll ll ll
ll from peroxisomes. Ribosomes are RNA-protein complexes (nucleoproteins) that are
ll ll ll ll ll ll ll ll
ll synthesized in the nucleolus and secreted into the cytoplasm through pores in the nuclear
ll ll ll ll ll ll ll ll ll ll ll ll ll
ll envelope called nuclear pore complexes. Lysosomes are saclike structures that originate
ll ll ll ll ll ll ll ll ll ll
ll from the Golgi complex and contain more than 40 digestive enzymes called hydrolases,
ll ll ll ll ll ll ll ll ll ll ll ll
ll which catalyze bonds in proteins, lipids, nucleic acids, and carbohydrates.

4. Which cell component is capable of cellular autodigestion when it is released during
ll ll ll ll ll ll ll ll ll ll ll ll
cellinjury?

a. Ribosome c. Smooth endoplasmic reticulum ll ll
b. Golgi complex ll d. Lysosomes
l l
ANS: D ll

, PATHOPHYSIOLOGY 8TH EDITION MCCANCE Huether TEST BANK ll ll ll ll ll ll
The lysosomal membrane acts as a protective shield between the powerful digestive
ll ll ll ll ll ll ll ll ll ll ll
enzymes within the lysosome and the cytoplasm, preventing their leakage into the
ll ll ll ll ll ll ll ll ll ll ll ll
cytoplasmic matrix. Disruption of the membrane by various treatments or cellular injury
ll ll ll ll ll ll ll ll ll ll ll ll
leads to a release of the lysosomal enzymes, which can then react with their specific
ll ll ll ll ll ll ll ll ll ll ll ll ll ll ll
substrates, causing cellular self-digestion. The other options do not correctly describe
ll ll ll ll ll ll ll ll ll ll ll
thisprocess.

5. What is the sequence of steps in the development of a digestive enzyme by the
ll ll ll ll ll ll ll ll ll ll ll ll ll ll
ll pancreascells from the initial transcription to the release from the cell?
l ll ll ll ll ll ll ll ll ll ll
a. The enzyme is transcribed from DNA by RNA in the nucleus, proceeds to
ll ll ll ll ll ll ll ll ll ll ll ll
theribosome for synthesis, and is transported in a secretory vesicle to the
ll l ll ll ll ll ll ll ll ll ll ll ll
cell membrane.
ll ll
b. The enzyme is transcribed from RNA by DNA in the nucleus, proceeds to the
ll ll ll ll ll ll ll ll ll ll ll ll ll
lysosome for synthesis, and is transported in an encapsulated membrane to the
ll ll ll ll ll ll ll ll ll ll ll ll
cellmembrane.
ll l
c. The enzyme is transcribed by the mitochondria in the nucleus, proceeds to the
ll ll ll ll ll ll ll ll ll ll ll ll
ribosome for synthesis, and is transported in a cytoskeleton to the cell
ll ll ll ll ll ll ll ll ll ll ll ll
membrane.
ll
d. The enzyme is transcribed from DNA by RNA in the nucleus, proceeds to the
ll ll ll ll ll ll ll ll ll ll ll ll ll
Golgi complex for synthesis, and is transported in a cytosol to the cell
ll ll ll ll ll ll ll ll ll ll ll ll ll
membrane.

ANS: A ll

ll ll ll ll ll ll ll ll ll ll ll ll ll
ribosomefor 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?
ll ll ll ll ll ll ll ll ll
a. G1 c. G2
b. S d. M l l
ANS: B ll
The four designated phases of the cell cycle are: (1) the G1 phase (G = gap), which is the
ll ll ll ll ll ll ll ll ll ll ll ll ll ll ll ll ll ll
period between the M phase (M = mitosis) and the start of DNA synthesis; (2) the S
ll ll ll ll ll ll ll ll ll ll ll ll ll ll ll ll ll
phase(S = synthesis), during which DNA is synthesized in the cell nucleus; (3) the G2
ll l ll ll ll ll ll ll ll ll ll ll ll ll ll ll
phase, during which RNA and protein synthesis occurs, the period between the
ll ll ll ll ll ll ll ll ll ll ll ll
