XRNA, Xmost Xof Xthe Xcellular XDNA, Xand Xthe XDNA-binding Xproteins, Xsuch Xas Xthe
Xhistones, Xwhich Xregulate Xits Xactivity. XThe Xmitochondria Xare Xresponsible Xfor Xcellular
Xrespiration Xand Xenergy Xproduction.
Ribosomes’ Xchief Xfunction Xis Xto Xprovide Xsites Xfor Xcellular Xprotein Xsynthesis.
XLysosomes Xfunction Xas Xthe Xintracellular Xdigestive Xsystem.

3. Which Xcomponent Xof Xthe Xcell Xproduces Xhydrogen Xperoxide X(H2O2) XbyXusing Xoxygen Xto
Xremove Xhydrogen Xatoms Xfrom Xspecific Xsubstrates Xin Xan Xoxidative Xreaction?
a. Lysosomes
b. Peroxisomes
c. Ribosomes
d. Endosome
ANS: X B
Peroxisomes Xare Xso Xnamed Xbecause Xthey Xusually Xcontain Xenzymes Xthat Xuse Xoxygen Xto
Xremove Xhydrogen Xatoms Xfrom Xspecific Xsubstrates Xin Xan Xoxidative Xreaction Xthat Xproduces
XH2O2, Xwhich Xis Xa Xpowerful Xoxidant Xand Xpotentially Xdestructive Xif Xit Xaccumulates Xor
Xescapes Xfrom Xperoxisomes. XRibosomes Xare XRNA-protein Xcomplexes X(nucleoproteins)
Xthat Xare Xsynthesized Xin Xthe Xnucleolus Xand Xsecreted Xinto Xthe Xcytoplasm Xthrough Xpores Xin
Xthe Xnuclear Xenvelope Xcalled Xnuclear Xpore Xcomplexes. XLysosomes Xare Xsaclike Xstructures
Xthat Xoriginate Xfrom Xthe XGolgi Xcomplex Xand Xcontain Xmore Xthan X40 Xdigestive Xenzymes
Xcalled Xhydrolases, Xwhich Xcatalyze Xbonds Xin Xproteins, Xlipids, Xnucleic Xacids, Xand
Xcarbohydrates. XAn Xendosome Xis Xa Xvesical Xthat Xhas Xbeen Xpinched Xoff Xfrom Xthe Xcellular
Xmembrane.

4. Which Xcell Xcomponent Xis Xcapable Xof Xcellular Xautodigestion Xwhen Xit Xis Xreleased
Xduring Xcell Xinjury?
, a. Ribosome
b. Golgi Xcomplex
c. Smooth Xendoplasmic Xreticulum
d. Lysosomes
ANS: X D
The Xlysosomal Xmembrane Xacts Xas Xa Xprotective Xshield Xbetween Xthe Xpowerful Xdigestive
Xenzymes Xwithin Xthe Xlysosome Xand Xthe Xcytoplasm, Xpreventing Xtheir Xleakage Xinto Xthe
Xcytoplasmic Xmatrix. XDisruption Xof Xthe Xmembrane Xby Xvarious Xtreatments Xor Xcellular
Xinjury Xleads Xto Xa Xrelease Xof Xthe Xlysosomal Xenzymes, Xwhich Xcan Xthen Xreact Xwith Xtheir
Xspecific Xsubstrates, Xcausing Xcellular
self-digestion. XThe Xchief Xfunction Xof Xa Xribosome Xis Xto Xprovide Xsites Xfor Xcellular Xprotein
Xsynthesis. XThe XGolgi Xcomplex Xis Xa Xnetwork Xof Xflattened, Xsmooth Xvesicles Xand
Xmembranes Xoften Xlocated Xnear Xthe Xcell Xnucleus. XThe Xsmooth Xendoplasmic Xreticulum Xis
