Some secretory cells synthesize and release glycoproteins. What is the correct order of the sequence of events as they occur in the secretory cell?

I. Exocytosis

II. Product accumulates in secretory vesicle

III. mRNA binds to ribosomes

IV. Synthesis of glycoprotein

Question

TestHub · Accepted Answer

Protein synthesis follows the typical transcription to translation steps. The mRNA having the code for glycoprotein will be translated by the ribosome possibly in the rough endoplasmic reticulum (RER). Later the constructed protein is processed by golgi bodies and secreted out of the cell via exocytosis in vesicles made out of the golgi bodies. Such secretory cells have a higher amount of RER and GB.
