Protein synthesis rer
WebbRough-endoplasmic reticulum - rER. The outer membrane of the rER is studded with ribosomes.This gives a basophilic staining to cytoplasm in H&E stains (due to the RNA content). The rER plays a major role in protein synthesis. It synthesises secretory proteins, and lysosomal enzymes. Cells active in secretion will have lots of rER - and you can see … WebbPrecisely, the RER segregates the polypeptides and amino acids from cytosol (the intracellular fluid), and assembles the proteins. It is here that the proteins are synthesized for other cell organelles like plasma …

WebbThe rough endoplasmic reticulum, or rough ER for short, is a network of membranous and flattened tubules that surround the nucleus of the cell. It is studded with ribosomes, which function to synthesize proteins for the cell. These proteins are destined to be exported from the cell, to be used in the cell membrane, or to be used in the lysosomes. Webb20 mars 2024 · endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins . All eukaryotic cells contain an endoplasmic reticulum (ER).

As they are sites of protein synthesis, they are found at places that are actively involved in protein synthesis. Not just synthesis, but they are present in sites of secretion of proteins. They are responsible for giving rise to the Smooth Endoplasmic Reticulum.
Webb20 okt. 2024 · The RER is studded with ribosomes, which are the sites of protein synthesis. The RER synthesizes proteins that are destined for export from the cell or for insertion into the cell membrane. The SER is involved in lipid synthesis. The SER synthesizes lipids, such as cholesterol and triglycerides.
