Chapter 1. The Cell as a Unit of Health and Disease
1 The nucleus _________, which is essential for function and
survival of the cell.
M
A) is the site of protein synthesis
O
B) contains the genetic code
.C
C) transforms cellular energy
LD
D) initiates aerobic metabolism
R
2 Although energy is not made in mitochondria, they are known
O
as the power plants of the cell because they:
W
A) contain RNA for protein synthesis.
KS
B) utilize glycolysis for oxidative energy.
C)
N
extract energy from organic compounds.
BA
D) store calcium bonds for muscle contractions.
ST
3 Although the basic structure of the cell plasma membrane is
formed by a lipid bilayer, most of the specific membrane
TE
functions are carried out by:
G
A) bound and transmembrane proteins.
N
B) complex, long carbohydrate chains.
SI
C) surface antigens and hormone receptors.
R
U
D) a gating system of selective ion channels.
.N
4 To effectively relay signals, cell-to-cell communication
W
utilizes chemical messenger systems that:
W
A) displace surface receptor proteins.
W
B) accumulate within cell gap junctions.
C) bind to contractile microfilaments.
D) release secretions into extracellular fluid.
, 5 Aerobic metabolism, also known as oxidative metabolism,
provides energy by:
A) removing the phosphate bonds from ATP.
B) combining hydrogen and oxygen to form
M
water.
O
C) activating pyruvate stored in the cytoplasm.
.C
D) breaking down glucose to form lactic acid.
LD
6 Exocytosis, the reverse of endocytosis, is important in
_______ into the extracellular fluid.
R
O
A) Engulfing and ingesting fluid and proteins for
W
transport
KS
B) Killing, degrading, and dissolving harmful
microorganisms
N
C) Removing cellular debris and releasing
BA
synthesized substances
ST
D) Destruction of particles by lysosomal enzymes
for secretion
TE
7 The process responsible for generating and conducting
G
membrane potentials is:
N
A) diffusion of current-carrying ions.
SI
B) millivoltage of electrical potential.
R
U
C) polarization of charged particles.
.N
D) ion channel neurotransmission.
W
8 Epithelial tissues are classified according to the shape of the
W
cells and the number of layers. Which of the following is a
correctly matched description and type of epithelial tissue?
W
A) Simple epithelium: cells in contact with
intercellular matrix; some do not extend to
surface
, B) Stratified epithelium: single layer of cells; all
cells rest on basement membrane
C) Glandular epithelium: arise from surface
epithelia and underlying connective tissue
M
D) Pseudostratified epithelium: multiple layers of
cells; deepest layer rests on basement
O
membrane
.C
LD
9 Connective tissue contains fibroblasts that are responsible for:
A) providing a fibrous framework for capillaries.
R
O
B) synthesis of collagen, elastin, and reticular
fibers.
W
C) forming tendons and the fascia that covers
KS
muscles.
D)
N
filling spaces between tissues to keep organs in
BA
place.
ST
10 Although all muscle tissue cells have some similarities,
smooth muscle (also known as involuntary muscle) differs
TE
by:
G
A) having dense bodies attached to actin
filaments.
N
SI
B) containing sarcomeres between Z lines and M
R
bands.
U
C) having rapid contractions and abundant cross-
.N
striations.
W
D) contracting in response to increased
W
intracellular calcium.
W
11 Which of the following aspects of the function of the nucleus
is performed by ribosomal RNA (rRNA)?
A) Copying and carrying DNA instructions for
protein synthesis
, B) Carrying amino acids to the site of protein
synthesis
C) Providing the site where protein synthesis
occurs
M
D) Regulating and controlling protein synthesis
O
12 Breakdown and removal of foreign substances and worn-out
.C
cell parts are performed by which of the following
LD
organelles?
A) Lysosomes
R
O
B) Golgi apparatus
W
C) Ribosomes
KS
D) Endoplasmic reticulum (ER)
13 Impairment in the function of peroxisomes would result in:
N
BA
A) inadequate sites for protein synthesis.
B) an inability to transport cellular products
ST
across the cell membrane.
TE
C) insufficient energy production within a cell.
G
D) accumulation of free radicals in the cytoplasm.
N
14 After several months of trying to conceive, a couple is
SI
undergoing fertility testing. Semen analysis indicates that the
R
mans sperm have decreased motility, a finding that is thought
U
to underlie the couples inability to become pregnant. Which
.N
of the following cellular components may be defective within
the mans sperm?
W
A) Ribosomes
W
B) Microtubules
W
C) Mitochondria
D) Microfilaments
