B) utilize cglycolysis cfor coxidative cenergy.
C) extract cenergy cfrom corganic ccompounds.
D) store ccalcium cbonds cfor cmuscle ccontractions.
3. Although cthe cbasic cstructure cof cthe ccell cplasma cmembrane cis cformed cby ca
clipid cbilayer, cmost cof cthe cspecific cmembrane cfunctions care ccarried cout
cby:
A) bound cand ctransmembrane cproteins.
B) complex, clong ccarbohydrate cchains.
C) surface cantigens cand chormone creceptors.
,D) a cgating csystem cof cselective cion cchannels.
4. To ceffectively crelay csignals, ccell-to-cell ccommunication cutilizes
cchemical cmessenger csystems cthat:
A) displace csurface creceptor cproteins.
B) accumulate cwithin ccell cgap cjunctions.
C) bind cto ccontractile cmicrofilaments.
D) release csecretions cinto cextracellular cfluid.
,5. Aerobic cmetabolism, calso cknown cas coxidative cmetabolism, cprovides cenergy cby:
, A) removing cthe cphosphate cbonds cfrom cATP.
B) combining chydrogen cand coxygen cto cform cwater.
C) activating cpyruvate cstored cin cthe ccytoplasm.
D) breaking cdown cglucose cto cform clactic cacid.
6. Exocytosis, cthe creverse cof cendocytosis, cis cimportant cin into
cthe cextracellular cfluid.
A) Engulfing cand cingesting cfluid cand cproteins cfor ctransport
B) Killing, cdegrading, cand cdissolving charmful cmicroorganisms
C) Removing ccellular cdebris cand creleasing csynthesized csubstances
D) Destruction cof cparticles cby clysosomal cenzymes cfor csecretion
7. The cprocess cresponsible cfor cgenerating cand cconducting cmembrane cpotentials cis:
A) diffusion cof ccurrent-carrying cions.
B) millivoltage cof celectrical cpotential.
C) polarization cof ccharged cparticles.
D) ion cchannel cneurotransmission.
8. Epithelial ctissues care cclassified caccording cto cthe cshape cof cthe ccells cand
cthe cnumber cof clayers. cWhich cof cthe cfollowing cis ca ccorrectly cmatched

B) Stratified cepithelium: csingle clayer cof ccells; call ccells crest con
cbasement cmembrane
C) Glandular cepithelium: carise cfrom csurface cepithelia cand
