Rough endoplasmic reticulum function

Endomembrane system

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins The rough endoplasmic reticulum, also called the RER, is involved with protein synthesis. The RER works by producing proteins and helping them fold properly. The RER gets its name from a series of studded ribosomes that produce proteins. The ribosomes are located on the cytosolic side of the endoplasmic reticulum, which is also called the ER

The function of the rough endoplasmic reticulum is to make proteins that are destined to be part of the endomembrane system, the plasma membrane, or are to be secreted Rough endoplasmic reticulum, series of connected flattened sacs, part of a continuous membrane organelle in the cytoplasm of eukaryotic cells, that plays a central role in protein synthesis. The RER is named for the appearance of its outer surface, which is studded with protein-synthesizing ribosomes

Ribosomes on the rough endoplasmic reticulum are called 'membrane bound' and are responsible for the assembly of many proteins. This process is called translation. Certain cells of the pancreas and digestive tract produce a high volume of protein as enzymes Functions. The endoplasmic reticulum serves many general functions, including the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus. Rough endoplasmic reticulum is also involved in protein synthesis
