A) Nucleus ? RNA
B) Lysosome ? Protein synthesis
C) Mitochondria ? Respiration
D) Cytoskeleton ? Microtubules
Correct Answer: B
Solution :
[b] Protein synthesis takes place in ribosomes, which are attached to surface of endoplasmic reticulum by ribophorin-I and ribophorin-II. About 50 hydrolytic enzymes are found in the lysosome. They include proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases and sulphatases. All lysosomal enzymes are acid hydrolases and optimally active at pH-5.0.
