Question

The plasma cells of the immune system are responsible for secreting protein antibodies into the bloodstream. Within the plasma cell, the antibody moves through several organelles in what order?
a. Ribosomes, endoplasmic reticulum, nucleolus, Golgi apparatus, vesicles
b. Ribosomes, Golgi apparatus, endoplasmic reticulum, lysosome
c. Ribosomes, Golgi apparatus, endoplasmic reticulum, vesicles
d. Ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles
e. Ribosomes, vesicles, endoplasmic reticulum, Golgi apparatus

Answer 1

Answer:

Ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles.

Explanation:

The endomembrane system in eukaryotes has divided the cell organelles into the structural and functional unit. This system plays an important role in the protein processing, its sorting and transport of protein.

The protein is prepared from the plasma cells. The antibodies is made on the ribosomes by the translation process. From the ribosomes, it will move to the endoplasmic reticulum for the glycosylation and protein folding. Then it moves to the golgi for the further protein packaging and processing. With the help of the vesicles it moves to its destination part in the cell.

Thus, the correct answer is option (d).
