2. Where is most of a cell’s genetic information, including RNA and DNA, contained?
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Lysosome
ANS: C z@
The nucleus contains the nucleolus, a small dense structure composed largely of RNA, most o
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
f the cellular DNA, and the DNA-
z@ z@ z@ z@ z@ z@

3. Which component of the cell produces hydrogen peroxide (H2O2) by using oxygen to remo
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
ve hydrogen atoms from specific substrates in an oxidative reaction?
z@ z@ z@ z@ z@ z@ z@ z@ z@
a. Lysosomes
b. Peroxisomes
c. Ribosomes
d. Endosome
ANS: B z@
, Peroxisomes are so named because they usually contain enzymes that use oxygen to remove
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
hydrogen atoms from specific substrates in an oxidative reaction that produces H2O2, which is
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z
@a powerful oxidant and potentially destructive if it accumulates or escapes from peroxisomes
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
.
Ribosomes are RNA- z@ z@
protein complexes (nucleoproteins) that are synthesized in the nucleolus and secreted into the
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z
@cytoplasm through pores in the nuclear envelope called nuclear pore complexes. Lysosomes
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
are saclike structures that originate from the Golgi complex and contain more than 40 digesti
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
ve enzymes called hydrolases, which catalyze bonds in proteins, lipids, nucleic acids, and car
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
bohydrates. An endosome is a vesical that has been pinched off from the cellular membrane.

4. Which cell component is capable of cellular autodigestion when it is released during cell injury?
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
a. Ribosome
b. Golgi complex z@
c. Smooth endoplasmic reticulum z@ z@
d. Lysosomes
ANS: D z@
The lysosomal membrane acts as a protective shield between the powerful digestive enzymes
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z
@within the lysosome and the cytoplasm, preventing their leakage into the cytoplasmic matrix.
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
Disruption of the membrane by various treatments or cellular injury leads to a release of the
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z
@lysosomal enzymes, which can then react with their specific substrates, causing cellular self-
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
digestion. The chief function of a ribosome is to provide sites for cellular protein synthesis. T

he Golgi complex is a network of flattened, smooth vesicles and membranes often located nea
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
r the cell nucleus. The smooth endoplasmic reticulum is involved in steroid hormone producti

z@ z@ z@ z@ z@ z@ z@
a. Increased heart rate and force of contractio z@ z@ z@ z@ z@ z@
n
b. Secretion of cortisol z@ z@
c. Increased retention of water z@ z@ z@
d. Breakdown of fat z@ z@
ANS: C z@
Antidiuretic hormone leads to increased retention of water in the body. Epinephrine causes in
z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@ z@
creases in heart rate and force of contraction. Increased cortisol secretion is due to ACTH. Br
