Function of Rough Endoplasmic Reticulum

Easy Biology Cellular Biology

In cellular biology, the endoplasmic reticulum (ER) plays a key role in the synthesis and processing of proteins and lipids. The ER is divided into two types: rough ER, which is studded with ribosomes, and smooth ER, which is free of ribosomes. Rough ER is involved in the synthesis of proteins destined for secretion or for use in the cell's membrane, while smooth ER is primarily involved in lipid synthesis and detoxification processes.

Which of the following statements accurately describes one of the functions of the rough endoplasmic reticulum?

The rough ER synthesizes proteins that are primarily utilized by the mitochondria.

The rough ER is involved in the synthesis of proteins that are secreted from the cell.

The rough ER is responsible for lipid synthesis and glucose metabolism.

The rough ER helps in the breakdown of cellular waste materials.
