4. Which of the following proteins whose syntheses are completed in the rough ER?
A. pyruvate kinase located in the cytosol
B. enzymes located in the lysosomes
C. histone H3
D. mitochondria matrix proteins
Homework Answers
Answer:- (B). enzymes located in the lysosomes
Lysosomes are membrane-bound vesicles containing digestive enzymes, including glycosidases, proteases, and sulfatases. Lysosomal enzymes are synthesized in the endoplasmic reticulum (ER), transported to the Golgi system and labelled for lysosomes by adding the mannose-6-phosphate label.
Lysosomes are formed by the Golgi apparatus with enzymes inside and budded into the cytoplasm. The enzymes in the lysosome are formed in the rough endoplasmic reticulum, which is then delivered via transport vesicles to the Golgi apparatus.
