MULTIPLE CHOICE 9a




1. Which statement best describes the cellular function of metabolic absorption?
9a 9a 9a 9a 9a 9a 9a 9a 9a




a. Cells can produce proteins. 9a 9a 9a




b. Cells can secrete digestive 9a 9a 9a




enzymes.
c. Cells can take in and use 9a 9a 9a 9a 9a




nutrients.
d. Cells can synthesize fats. 9a 9a 9a




ANS: 9 a C
In metabolic absorption, all cells take in and use nutrients and other
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




substances from their surroundings. The remaining options are not
9a 9a 9a 9a 9a 9a 9a 9a 9a




inclusive in their descriptions of cellular metabolic absorption.

2. Where is most of a cell’s genetic information, including RNA and DNA,
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




contained?
9a




a. Mitochond
ria
b. Ribosome
c. Nucleolus
d. Lysosome
ANS: 9 a C
The nucleus contains the nucleolus, a small dense structure composed
9a 9a 9a 9a 9a 9a 9a 9a 9a




largely of RNA, most of the cellular DNA, and the DNA-binding proteins, such
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




as the histones, which regulate its activity. The mitochondria are
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




responsible for cellular respiration and energy production.
9a 9a 9a 9a 9a 9a 9a




Ribosomes’ chief function is to provide sites for cellular protein synthesis. Lysosomes
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




function as the intracellular digestive system.
9a 9a 9a 9a 9a 9a

3. Which component of the cell produces hydrogen peroxide (H2O2) by using
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




oxygen to remove hydrogen atoms from specific substrates in an oxidative
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




reaction?
9a




a. Lysosome
s
b. Peroxisom

, es
c. Ribosome
s
d. Endosome

ANS: 9 a B

, Peroxisomes are so named because they usually contain enzymes that use oxygen to
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




remove hydrogen atoms from specific substrates in an oxidative reaction that
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




produces H2O2, which is a powerful oxidant and potentially destructive if it
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




accumulates or escapes from peroxisomes. Ribosomes are RNA-protein complexes
9a 9a 9a 9a 9a 9a 9a 9a 9a




(nucleoproteins) that are synthesized in the nucleolus and secreted into the
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




cytoplasm through pores in the nuclear envelope called nuclear pore complexes.
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




Lysosomes are saclike structures that originate from the Golgi complex and contain
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




more than 40 digestive enzymes called hydrolases, which catalyze bonds in
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




proteins, lipids, nucleic acids, and carbohydrates. An endosome is a vesical that has
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




been pinched off from the cellular membrane.

4. Which cell component is capable of cellular autodigestion when it is
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




released during cell injury?
9a 9a 9a 9a




a. Ribosome
b. Golgi complex 9a




c. Smooth endoplasmic 9a




reticulum
d. Lysosomes
ANS: 9 a D
The lysosomal membrane acts as a protective shield between the powerful
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




digestive enzymes within the lysosome and the cytoplasm, preventing
9a 9a 9a 9a 9a 9a 9a 9a 9a




their leakage into the cytoplasmic matrix. Disruption of the membrane by
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




various treatments or cellular injury leads to a release of the lysosomal
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




enzymes, which can then react with their specific substrates, causing
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




cellular self- digestion. The chief function of a ribosome is to provide sites
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




for cellular protein synthesis. The Golgi complex is a network of flattened,
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




smooth vesicles and membranes often located near the cell nucleus. The
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




smooth endoplasmic reticulum is involved in steroid hormone production
9a 9a 9a 9a 9a 9a 9a 9a 9a




and removing toxic substances from the cell.

5. Which cAMP-mediated response is related to antidiuretic hormone?
9a 9a 9a 9a 9a 9a 9a




a. Increased heart rate and force of 9a 9a 9a 9a 9a




contraction
b. Secretion of cortisol 9a 9a




c. Increased retention of water 9a 9a 9a




d. Breakdown of fat 9a 9a




ANS: 9 a C
Antidiuretic hormone leads to increased retention of water in the body. 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




Epinephrine causes increases in heart rate and force of contraction. Increased
9a 9a 9a 9a 9a 9a 9a 9a 9a 9a 9a




cortisol secretion is due to ACTH. Breakdown of fat is due to glucagon.

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