Chapter .1. .The .Cell .as .a .Unit .of .Health .and .Disease
1 The .nucleus . , .which .is .essential .for .function .and
.survival .of .the .cell.
A) is .the .site .of .protein .synthesis
B) contains .the .genetic .code
C) transforms .cellular .energy
D) initiates .aerobic .metabolism
2 Although .energy .is .not .made .in .mitochondria, .they .are .known
.as .the .power .plants .of .the .cell .because .they:
A) contain .RNA .for .protein .synthesis.
B) utilize .glycolysis .for .oxidative .energy.
C) extract .energy .from .organic .compounds.
D) store .calcium .bonds .for .muscle .contractions.
3 Although .the .basic .structure .of .the .cell .plasma .membrane .is
.formed .by .a .lipid .bilayer, .most .of .the .specific .membrane
.functions .are .carried .out .by:
A) bound .and .transmembrane .proteins.
B) complex, .long .carbohydrate .chains.
C) surface .antigens .and .hormone .receptors.
D) a .gating .system .of .selective .ion .channels.
4 To .effectively .relay .signals, .cell-to-cell .communication
.utilizes .chemical .messenger .systems .that:
A) displace .surface .receptor .proteins.
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
.water.
C) activating .pyruvate .stored .in .the .cytoplasm.
D) breaking .down .glucose .to .form .lactic .acid.
6 Exocytosis, .the .reverse .of .endocytosis, .is .important .in
.into .the .extracellular .fluid.
A) Engulfing .and .ingesting .fluid .and .proteins .for .
.transport
B) Killing, .degrading, .and .dissolving .harmful
.microorganisms
C) Removing .cellular .debris .and .releasing .
.synthesized .substances
D) Destruction .of .particles .by .lysosomal .enzymes
.for .secretion
7 The .process .responsible .for .generating .and .conducting
.membrane .potentials .is:
A) diffusion .of .current-carrying .ions.
B) millivoltage .of .electrical .potential.
C) polarization .of .charged .particles.
D) ion .channel .neurotransmission.
8 Epithelial .tissues .are .classified .according .to .the .shape .of .the
.cells .and .the .number .of .layers. .Which .of .the .following .is .a
.correctly . matched .description .and .type .of .epithelial .tissue?
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
D) Pseudostratified .epithelium: .multiple .layers .of
.cells; .deepest .layer .rests .on .basement
.membrane
9 Connective .tissue .contains .fibroblasts .that .are .responsible .for:
A) providing .a .fibrous .framework .for .capillaries.
B) synthesis .of .collagen, .elastin, .and .reticular
.fibers.
C) forming .tendons .and .the .fascia .that .covers .
.muscles.
D) filling .spaces .between .tissues .to .keep .organs .in
.place.
10 Although .all .muscle .tissue .cells .have .some .similarities,
.smooth .muscle .(also .known .as .involuntary .muscle) .differs
.by:
A) having .dense .bodies .attached .to .actin .
.filaments.
B) containing .sarcomeres .between .Z .lines .and .M
.bands.
C) having .rapid .contractions .and .abundant .cross-
.striations.
D) contracting .in .response .to .increased
.intracellular .calcium.
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
