Question

Quizplus · Accepted Answer

The endoplasmic reticulum (ER) is responsible for protein synthesis and processing, including the synthesis of proteins that are destined for secretion by the cell. This process occurs on the rough ER, where ribosomes are attached to the surface. The proteins are then modified and processed in the ER before being transported to the Golgi apparatus for further processing and eventual secretion.
