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?

Question

Quizplus · Accepted Answer

The correct order is ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles. The antibody is initially synthesized by ribosomes, then transported to the endoplasmic reticulum for folding and modification. From there, it moves to the Golgi apparatus for further modification and sorting before being packaged into vesicles for secretion. Lysosomes are not involved in this process. The nucleolus is also not involved as it is responsible for producing ribosomes, not processing antibodies.
