Chapter z 1. zThe z Cell z as z a z Unit z of z Health z and z Disease
1 The z nucleus , z which z is z essential z for z function
z andzsurvival z of zthe zcell.
A) is z the zsite z of z protein z synthesis
B) contains z the z genetic z code
C) transforms z cellular z energy
D) initiates z aerobic z metabolism
2 Although zenergy zis znot zmade zin zmitochondria, zthey zare
zknownzas zthe z power z plants z of zthe z cell zbecause z they:
A) contain z RNA zfor z protein z synthesis.
B) utilize z glycolysis z for z oxidative z energy.
C) extract z energy z from z organic z compounds.
D) store z calcium z bonds z for z muscle z contractions.
3 Although z the z basic z structure z of z the z cell z plasma z membrane
z iszformed zby za zlipid zbilayer, zmost zof zthe zspecific zmembrane
zfunctions zare z carried zout zby:
A) bound z and z transmembrane z proteins.
B) complex, z long z carbohydrate z chains.
C) surface z antigens z and z hormone z receptors.
D) a z gating z system z of z selective z ion z channels.
4 To z effectively z relay z signals, z cell-to-cell
z communicationzutilizes z chemical z messenger z systems z that:
A) displace z surface z receptor z proteins.
B) accumulate z within z cell z gap z junctions.
C) bind z to z contractile z microfilaments.
D) release z secretions z into z extracellular z fluid.
,5 Aerobic z metabolism, z also z known z as z oxidative
z metabolism,zprovides z energy zby:
A) removing zthe z phosphate zbonds z from zATP.
B) combining z hydrogen z and z oxygen z to
z formzwater.
C) activating z pyruvate z stored z in z the z cytoplasm.
D) breaking z down z glucose z to z form z lactic z acid.
6 Exocytosis, z the z reverse z of z endocytosis, z is z important z in
z into z the z extracellular z fluid.
A) Engulfing z and z ingesting z fluid z and z proteins z for
transport
B) Killing, z degrading, z and z dissolving
z harmfulzmicroorganisms
C) Removing z cellular z debris z and z releasing
synthesized z substances
D) Destruction z of z particles z by z lysosomal
z enzymeszfor zsecretion
7 The z process z responsible z for z generating z and
z conductingzmembrane zpotentials z is:
A) diffusion z of z current-carrying z ions.
B) millivoltage z of z electrical z potential.
C) polarization z of z charged z particles.
D) ion z channel z neurotransmission.
8 Epithelial z tissues z are z classified z according z to z the z shape z of
z thezcells z and z the z number z of z layers. z Which z of z the z following
z is z a zcorrectly z matched z description z and z type z of z epithelial
z tissue?
A) Simple z epithelium: z cells z in z contact z with
zintercellular zmatrix; zsome zdo znot zextend
ztozsurface
, B) Stratified z epithelium: z single z layer z of z cells;
z allzcells z rest z on zbasement z membrane
C) Glandular z epithelium: z arise z from z surface
epithelia z and z underlying z connective
z tissue
D) Pseudostratified z epithelium: z multiple z layers
z ofzcells; z deepest z layer z rests z on zbasement
zmembrane
9 Connective z tissue z contains z fibroblasts z that z are z responsible
z for:
A) providing z a z fibrous z framework z for z capillaries.
B) synthesis z of z collagen, z elastin, z and
z reticularzfibers.
C) forming z tendons z and zthe z fascia z that z covers
muscles.
D) filling z spaces z between z tissues z to z keep z organs
z inzplace.
10 Although zall zmuscle ztissue zcells zhave zsome zsimilarities,
zsmooth z muscle z (also z known z as z involuntary z muscle)
z differszby:
A) having z dense z bodies z attached z to
z actinzfilaments.
B) containing z sarcomeres z between z Z z lines z and
z Mzbands.
C) having z rapid z contractions z and z abundant z cross-
striations.
D) contracting z in z response z to
z increasedzintracellular zcalcium.
11 Which z of z the z following z aspects z of z the z function z of z the
z nucleuszis z performed zby zribosomal z RNA z(rRNA)?
A) Copying z and z carrying z DNA zinstructions
z forzprotein zsynthesis
