,Chapter’‘1.’‘Cellular’‘Biology

MULTIPLE’‘CHOICE

1. A’‘student’‘is’‘observing’‘a’‘cell’‘under’‘the’‘microscope.’‘It’‘is’‘observed’‘to’‘have’‘supercoiled
’‘DNA’‘with’‘histones.’‘Which’‘of’‘the’‘following’‘would’‘also’‘be’‘observed’‘by’‘the’‘student?


a. A’‘single’‘circular’‘chromosome
b. A’‘nucleus
c. Free-floating’‘nuclear’‘material
d. No’‘organelles


ANS:’‘B

The’‘cell’‘described’‘is’‘a’‘eukaryotic’‘cell,’‘so’‘it’‘has’‘histones’‘and’‘a’‘supercoiled’‘DNA’‘within’‘
its’‘nucleus;’‘thus,’‘the’‘nucleus’‘should’‘be’‘observed.

A’‘single’‘circular’‘chromosome’‘is’‘characteristic’‘of’‘prokaryotic’‘cells,’‘which’‘do’‘not’‘have’‘histones.

Free-
floating’‘nuclear’‘material’‘describes’‘a’‘prokaryotic’‘cell,’‘which’‘would’‘not’‘have’‘a’‘distinct’‘nuc
leus.

Eukaryotic’‘cells’‘have’‘membrane’‘bounded’‘cellular’‘components’‘called’‘organelles.’‘No’‘organelles’‘
describes’‘a’‘prokaryotic’‘cell.

2. A’‘nurse’‘is’‘instructing’‘the’‘staff’‘about’‘cellular’‘functions.’‘Which’‘cellular’‘function’‘is’‘the’
‘nurse’‘describing’‘when’‘an’‘isolated’‘cell’‘absorbs’‘oxygen’‘and’‘uses’‘it’‘to’‘transform’‘nutrient

s’‘to’‘energy?

a. Metabolic’‘absorption
b. Communication
c. Secretion
d. Respiration

,ANS:’‘D

The’‘ability’‘of’‘the’‘cell’‘to’‘absorb’‘oxygen’‘refers’‘to’‘the’‘cells’‘function’‘of’‘respiration.

The’‘ability’‘of’‘the’‘cell’‘to’‘function’‘within’‘a’‘society’‘of’‘cells’‘refers’‘to’‘its’‘function’‘of’‘comm
unication.

The’‘ability’‘of’‘the’‘cell’‘to’‘take’‘in’‘nutrients’‘refers’‘to’‘the’‘cells’‘function’‘of’‘metabolic’‘absorption.

The’‘ability’‘of’‘the’‘cell’‘to’‘synthesize’‘new’‘substances’‘and’‘secrete’‘these’‘elsewhere’‘refers’‘to’‘the’‘c
ells’‘function’‘of’‘secretion.

3. A’‘eukaryotic’‘cell’‘is’‘undergoing’‘DNA’‘replication.’‘In’‘which’‘region’‘of’‘the’‘cell’‘would’‘m
ost’‘of’‘the’‘genetic’‘information’‘be’‘contained?

a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus


ANS:’‘C

The’‘region’‘of’‘the’‘cell’‘that’‘contains’‘genetic’‘material,’‘including’‘a’‘large’‘amount’‘of’‘ribonucl
eic’‘acid,’‘most’‘of’‘the’‘DNA,’‘and’‘DNA-binding’‘proteins,’‘is’‘the’‘nucleolus.

The’‘mitochondria’‘is’‘the’‘site’‘of’‘cellular’‘respiration.

The’‘ribosomes’‘are’‘involved’‘in’‘manufacturing’‘of’‘proteins’‘within’‘the’‘cell.

The’‘nucleus’‘contains’‘the’‘nucleolus,’‘and’‘it’‘is’‘the’‘nucleolus’‘that’‘contains’‘genetic’‘material.

4. The’‘fluid’‘mosaic’‘model’‘for’‘biologic’‘membranes’‘describes’‘membrane’‘behavior.’‘Accordi
ng’‘to’‘this’‘model,’‘which’‘of’‘the’‘following’‘float’‘singly’‘or’‘as’‘aggregates’‘in’‘the’‘fluid’‘lipid’‘
bilayer?

a. Peripheral’‘membrane’‘proteins
b. Integral’‘membrane’‘proteins

, c. Glycoproteins
d. Cell’‘adhesion’‘molecules


ANS:’‘B

Integral’‘membrane’‘proteins’‘float’‘freely’‘in’‘the’‘fluid’‘lipid’‘bilayer.

Peripheral’‘membrane’‘proteins’‘are’‘not’‘embedded’‘in’‘the’‘layer,’‘but’‘reside’‘at’‘the’‘surface.’‘Gl

ycoproteins’‘act’‘as’‘cell’‘surface’‘markers.

Cell’‘adhesion’‘molecules’‘are’‘on’‘the’‘outside’‘of’‘the’‘membrane’‘and’‘allow’‘cells’‘to’‘hook’‘together.

5. Which’‘of’‘the’‘following’‘can’‘bind’‘to’‘plasma’‘membrane’‘receptors?

a. Oxygen
b. Ribosomes
c. Amphipathic’‘lipids
d. Ligands


ANS:’‘D

Ligands’‘are’‘specific’‘molecules’‘that’‘can’‘bind’‘with’‘receptors’‘on’‘the’‘cell’‘membrane.’‘

Oxygen’‘moves’‘by’‘diffusion;’‘it’‘does’‘not’‘bind’‘to’‘receptors.

Ribosomes’‘make’‘proteins’‘and’‘are’‘not’‘involved’‘in’‘bindi

ng.’‘Amphipathic’‘lipids’‘are’‘a’‘portion’‘of’‘the’‘cell’‘memb

rane.

6. A’‘nurse’‘is’‘reviewing’‘a’‘report’‘from’‘a’‘patient’‘with’‘metastatic’‘cancer.’‘What’‘finding’‘
would’‘support’‘the’‘diagnosis’‘of’‘metastatic’‘cancer?’‘Alterations’‘in’‘extracellular’‘matrix’‘t
hat’‘include:

a. Decreased’‘fibronectin
b. Increased’‘collagen
c. Decreased’‘elastin
