MULTIPLE CHOICE
• Mitochondria produce which chemical for intracellular energy?
• ADP
• ATP
• RNA
• DNAANS: B
Feedback
A Mitochondria generate energy through ATP, not ADP, production. B
Correct. Mitochondria produce energy via ATP.
C Mitochondria generate energy through ATP, not RNA, production. D
Mitochondria generate energy through ATP, not DNA, production.
DIF: Recall REF: pp. 2-3 OBJ: 1
• Each tissue originates from mesoderm, EXCEPT one. Which is the
EXCEPTION?
• Bone
• Liver
• Blood
• MuscleANS: B
Feedback
• Bone tissue develops from mesodermal cells.
• Correct. Liver tissue is produced by endodermal cells. C Blood
develops from mesodermal cells.
D Muscle tissue develops from mesodermal cells. DIF: Recall REF: p.
6 OBJ: 3
• Which chemical is called the second messenger?
• aDNA
• mRNA
• dGMP
,• cAMPANS: D
Feedback
A cAMP is the second messenger; aDNA is not. B cAMP is the
second messenger; mRNA is not. C cAMP is the second messenger; dGMP
is not.
D Correct. cAMP transmits information to the intracellular organelles when
activated by surface receptors on the plasma membrane.
DIF: Recall REF: p. 3 OBJ: 3
• Which cellular component facilitates protein synthesis?
• Ribosomes
• Lysosomes
• Mitochondria
• Plasmalemma ANS: A
Feedback
• Correct. Ribosomes synthesize protein.
• Lysosomes facilitate the breakdown of intracellular and extracellular
substances. C Mitochondria generate energy.
D The plasmalemma provides a protective barrier and regulates the
transport ofsubstances to and from the cell.
• Which organelle produces microtubules?
• Nucleus
• Centriole
• Golgi apparatus
• Endoplasmic reticulum ANS: B
Feedback
A Centrioles generate microtubules; the nucleus does not. B Correct.
Centrioles produce microtubules.
• Centrioles generate microtubules; the Golgi apparatus does not.
• Centrioles generate microtubules; the endoplasmic reticulum does
not. DIF: Recall REF: p. 3 OBJ: 1
• Which phase of the cell cycle is characterized as the initial resting
stage?
, • S phase
• G1 phase
• G2 phase
• Prophase ANS: B
Feedback
A The S phase is characterized as the stage in which DNA synthesis is
complete. B Correct. The G1 phase is the initial resting stage.
• The G2 phase is characterized by post-DNA duplication.
• Prophase is characterized by four specific structural changes. DIF:
Recall REF: p. 4 OBJ: 1
• Posttranslational modifications to proteins produced by the rough
endoplasmic reticulumare
accomplished by .
• mitochondria
• Golgi apparatus
• messenger RNA
• smooth endoplasmic reticulum ANS: B
Feedback
• The Golgi apparatus is responsible for posttranslational alterations;
mitochondriaare not.
• Correct. The Golgi apparatus makes alterations to proteins produced
by therough endoplasmic reticulum.
• The Golgi apparatus is responsible for posttranslational alterations;
mRNA is not.
• The Golgi apparatus is responsible for posttranslational alterations;
the smoothendoplasmic reticulum is not.
DIF: Recall REF: p. 2 OBJ: 1
• The provides an ideal environment for the implantation and
growth of the embryo.
• ovary
• uterine tube
• myometrium
• endometrium ANS: DFeedback
