a. Cells can produce proteins. pn pn pn



b. Cells can secrete digestive enzymes. pn pn pn pn

ANS: C p n



In metabolic absorption, all cells take in and use nutrients and other substances from their surr

2. Where is most of a cell’s genetic information, including RNA and DNA, contained?
pn pn pn pn pn pn pn pn pn pn pn pn



a. Mitochondria
b. Ribosome
c. Nucleolus
d. Lysosome
ANS: C p n



The nucleus contains the nucleolus, a small dense structure composed largely of RNA, most
pn pn pn pn pn pn pn pn pn pn pn pn pn pn



of the cellular DNA, and the DNA-
pn pn pn pn pn pn



binding proteins, such as the histones, which regulate its activity. The mitochondria are respo

3. Which component of the cell produces hydrogen peroxide (H2O2) by using oxygen to remove
pn pn pn pn pn pn pn pn pn pn pn pn pn pn



hydrogen atoms from specific substrates in an oxidative reaction?
pn pn pn pn pn pn pn pn



a. Lysosomes
b. Peroxisomes
c. Ribosomes
d. Endosome
ANS: B p n

, Peroxisomes are so named because they usually contain enzymes that use oxygen to remove h

ydrogen 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- pn pn



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 a

hydrates. 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
pn pn pn pn pn pn pn pn pn pn pn pn pn pn



injury?
a. Ribosome
b. Golgi complex pn



c. Smooth endoplasmic reticulum pn pn



d. Lysosomes
ANS: D p n



The lysosomal membrane acts as a protective shield between the powerful digestive enzymes
pn pn pn pn pn pn pn pn pn pn pn pn pn



within the lysosome and the cytoplasm, preventing their leakage into the cytoplasmic matrix.
pn pn pn pn pn pn pn pn pn pn pn pn pn



Disruption of the membrane by various treatments or cellular injury leads to a release of the l

The Golgi complex is a network of flattened, smooth vesicles and membranes often located n

5. Which cAMP-mediated response is related to antidiuretic hormone?
pn pn pn pn pn pn pn



a. Increased heart rate and force of contraction pn pn pn pn pn pn



b. Secretion of cortisol pn pn



c. Increased retention of water pn pn pn



d. Breakdown of fat pn pn




ANS: C p n



Antidiuretic hormone leads to increased retention of water in the body. Epinephrine causes increa

6. During which phase of the cell cycle is DNA synthesized?
pn pn pn pn pn pn pn pn pn



a. G1
