ANS: jC
The jregion jof jthe jcell jthat jcontains jgenetic jmaterial, jincluding ja jlarge jamount jof jribonucleic
jacid, jmost jof jthe jDNA, jand jDNA-binding jproteins, jis jthe jnucleolus.
The jmitochondria jis jthe jsite jof jcellular jrespiration.
The jribosomes jare jinvolved jin jmanufacturing jof jproteins jwithin jthe jcell.

a. Peripheral jmembrane jproteins
b. Integral jmembrane jproteins
, c. Glycoproteins
d. Cell jadhesion jmolecules
ANS: jB
Integral jmembrane jproteins jfloat jfreely jin jthe jfluid jlipid jbilayer.
Peripheral jmembrane jproteins jare jnot jembedded jin jthe jlayer, jbut jreside jat jthe jsurface.
jGlycoproteins jact jas jcell jsurface jmarkers.
Cell jadhesion jmolecules jare jon jthe joutside jof jthe jmembrane jand jallow jcells jto jhook jtogether.
