Question

Lysosomes consist of

A.   vesicles containing digestive enzymes that are synthesized by ribosomes on the Golgi where they are packaged

B.   vesicles containing digestive enzymes that are synthesized by ribosomes on the RER, then sent to the Golgi where they are packaged

C.   vesicles containing digestive enzymes that are synthesized by ribosomes on the Golgi, then sent to the RER where they are packaged

D.   vesicles synthesized on the nuclear envelope, sent to the RER, then the Golgi where they are packaged

E.   a double membrane derived from both the RER and the Golgi

Explanation / Answer

Option B is correct.

All enzymes are proteins.

Enzymes are synthesized in the form of proteins. mRNA binds to the ribosome and then binds to the RER and then synthesize proteins and the transport into ER.

After the protein present in ER is transported to the golgi in the form vescicle.
