WebbThe endoplasmic reticulum (ER) is an important organelle in eukaryotic cells. It plays a major role in the production, processing, and transport of proteins and lipids. The ER produces transmembrane proteins and lipids for its membrane and for many other cell components including lysosomes, secretory vesicles, the Golgi appatatus, the cell ... Webb6 apr. 2024 · Secretory proteins are synthesized in a form of precursors with additional sequences at their N-terminal ends called signal peptides. The signal peptides are recognized co-translationally by signal recognition particle (SRP). This interaction leads to targeting to the endoplasmic reticulum (ER) membrane and translocation of the nascent …
WebbRibosomes are the smallest cell organelles which can be seen only through an electron microscope. They are found in both prokaryotic as well as eukaryotic cells. Ribosomes are dense, round bodies which occur freely in the cytoplasm and may remain attached to the surface of the endoplasmic reticulum.
