A cell with a predominance of rough endoplasmic reticulum is most likely ________. A) producing large quantities of proteins for secretion B) producing large quantities of proteins in the cytosol C) producing large quantities of carbohydrates to assemble an extensive cell wall matrix D) producing large quantities of carbohydrates for storage in the vacuole

Explanation:the rough endoplasmic reticulum is a cell organelle that has ribobomes attached to it.the ribobomes attached gives it a coarse appearance. Rough endoplasmic reticulum is involved in the production of protein to be transported out of the cell.

The ribosomes pack amino acid into the proteins and then passes it to the rough endoplasmic reticulum.from there it is pass to the cis end of the Golgi apparatus.in the Golgi apparatus,further modifications takes place and the proteins is transported out of the cell.

Free ribobomes synthesize proteins meant for the cytosol.

The smooth endoplasmic reticulum synthesis non-protein molecules such as steroids and lipids.
