MULTIPLE aCHOICE

1. Which astatement abest adescribes athe acellular afunction aof ametabolic aabsorption?
a. Cells acan aproduce aproteins. c. Cells acan atake ain aand ause anutrients.

, b. Cells acan asecrete adigestive aenzymes. d. a Cells acan asynthesize afats.
ACCURATE aANSWER:-C
Reasoning:->>>In ametabolic aabsorption, aall acells atake ain aand ause anutrients aand aother
asubstances afrom atheir asurroundings. aThe aremaining aoptions aare anot ainclusive ain atheir

adescriptions aof acellular ametabolic aabsorption.

2. Most aof aa acell’s agenetic ainformation, aincluding aRNA aand aDNA, ais acontained ain athe:
a. Mitochondria c. Nucleolus
b. Ribosome d. a a Lysosome
ACCURATE aANSWER:-C
Reasoning:->>>The anucleus acontains athe anucleolus, aa asmall adense astructure acomposed
alargely aof aRNA, amost aof athe acellular aDNA, aand athe aDNA-binding aproteins, asuch aas

athe ahistones, awhich aregulate aits aactivity. aThe aother aoptions ado anot acontain amost aof aa

acell’s agenetic ainformation.

3. Which acomponent aof athe a cell aprodNuUceRsSIhNyGd TroBg. CenO M
p eroxide a(H2O2) aby ausing
aoxygen ato aremove ahydrogen aatoms afrom aspecific asubstrates ain aan aoxidative
areaction?

a. Lysosomes c. Ribosomes
b. Peroxisomes d. a Oxyhydrosomes

ACCURATE aANSWER:-B
Reasoning:->>>Peroxisomes aare aso anamed abecause athey ausually acontain aenzymes athat
ause aoxygen ato aremove ahydrogen aatoms afrom aspecific asubstrates ain aan aoxidative

areaction athat aproduces aH2O2, awhich ais aa apowerful aoxidant aand apotentially adestructive

aif ait aaccumulates aor aescapes afrom aperoxisomes. a Ribosomes aare aRNA-protein

acomplexes a(nucleoproteins) athat aare a synthesized a in athe anucleolus aand a secreted ainto athe

acytoplasm athrough apores ain athe anuclear aenvelope acalled anuclear apore acomplexes.

aLysosomes aare asaclike astructures athat aoriginate afrom athe aGolgi a complex aand acontain

amore athan a40 adigestive aenzymes acalled ahydrolases, awhich acatalyze abonds ain aproteins,

alipids, anucleic aacids, aand acarbohydrates. aOxyhydrosomes aare ainvolved ain a enzyme

aproduction.

4. Which acell acomponent ais acapable aof acellular aautodigestion awhen ait ais areleased aduring
cell ainjury?
a

a. Ribosome c. Smooth aendoplasmic areticulum
b. Golgi acomplex d. a Lysosomes

ACCURATE aANSWER:-D

, Reasoning:->>>The alysosomal amembrane aacts aas aa aprotective ashield abetween athe
apowerful adigestive aenzymes awithin athe alysosome aand athe acytoplasm, ablocking atheir

aleakage ainto athe acytoplasmic amatrix. aDisruption a of athe amembrane aby avarious

atreatments aor a cellular ainjury aleads ato aa arelease aof athe alysosomal a enzymes, awhich a can

athen areact awith atheir aspecific asubstrates, acausing acellular aself-digestion. aThe aother

aoptions ado anot acorrectly adescribe athis aprocess.

5. What ais athe asequence aof asteps ain athe adevelopment aof aa adigestive aenzyme aby athe
apancreas acells afrom athe ainitial atranscription ato athe arelease afrom athe acell?
a. The aenzyme ais atranscribed afrom aDNA aby aRNA ain athe anucleus, aproceeds ato
the aribosome afor asynthesis, aand ais aconducted ain aa asecretory avesicle ato athe
a

cell amembrane.
a

b. The aenzyme ais atranscribed afrom aRNA aby aDNA ain athe anucleus, aproceeds ato
athe alysosome afor asynthesis, aand ais aconducted ain aan aencapsulated amembrane ato

athe acell amembrane.

c. The aenzyme ais atranscribed aby athe amitochondria ain athe anucleus, aproceeds ato
athe aribosome afor asynthesis, aand ais aconducted ain aa acytoskeleton ato athe acell

amembrane.

d. The aenzyme ais atranscribed afrom aDNA aby aRNA ain athe anucleus, aproceeds ato
athe aGolgi acomplex afor asynthesis, aand ais aconducted ain aa acytosol ato athe acell

amembrane.



ACCURATE aANSWER:-A
Reasoning:->>>The aenzyme ais atranscribed afrom aDNA aby aRNA ain athe anucleus,
aproceeds ato athe aribosome afor asynthesis, aand ais aconducted ain a a a secretory avesicle ato athe

acell amembrane. aThe aother aoptions ado anot acorrectly adescribe athis aprocess.

6. During awhich aphase aof athe acell acycle ais aDNA asynthesized?
a. G1 c. G2
b. S d. a M

ACCURATE aANSWER:-B
Reasoning:->>>The afour adesignated aphases aof athe acell acycle aare: a(1) athe aG1 aphase a(G
a= agap), awhich ais athe aperiod abetween athe aM aphase a(M a= amitosis) aand athe astart aof aDNA


asynthesis; a(2) athe aS aphase a(S a= asynthesis), aduring awhich a DNA ais a synthesized ain athe

acell anucleus; a(3) athe aG2 aphase, aduring awhich a RNA aand aprotein asynthesis aoccurs, athe

aperiod abetween athe acompletion aof a DNA a synthesis aand athe anext aphase a(M); aand a(4) athe

aM aphase, awhich aincludes anuclear aand acytoplasmic adivision.

7. What aorganic acompound afacilitates atransportation aacross acell amembranes aby aacting
aas areceptors, atransportation/transport achannels afor aelectrolytes, aand aenzymes ato
adrive aactive apumps?
