Wat doet het glad endoplasmatisch reticulum?

Het glad ER (Engels: smooth ER, SER) is een variant van het endoplasmatisch reticulum dat voornamelijk dient om stoffen vanuit het ruw endoplasmatisch reticulum te vervoeren naar het golgiapparaat. Het bevindt zich dan ook vaak tussen zones met ruw endoplasmatisch reticulum en het golgiapparaat.

Wat is het verschil tussen glad en ruw endoplasmatisch reticulum?

Het endoplasmatisch reticulum (ER) bevat twee gebieden die verschillen in structuur en functie: het glad endoplasmatisch reticulum en het ruw endoplasmatisch reticulum. Het ruw ER heeft ribosomen op het membraan; het glad ER niet.

What are endomembrane ribosomes?

Ribosomes are made up of a large subunit (top) and a small subunit (bottom). During protein synthesis, ribosomes assemble amino acids into proteins. Before we discuss the endomembrane system, it’s essential to have an understanding of ribosomes. Ribosomes are the cellular structures responsible for protein synthesis.

What are ribosomes made up of?

Figure 1. Ribosomes are made up of a large subunit (top) and a small subunit (bottom). During protein synthesis, ribosomes assemble amino acids into proteins. Before we discuss the endomembrane system, it’s essential to have an understanding of ribosomes. Ribosomes are the cellular structures responsible for protein synthesis.

What is not included in the endomembrane system?

Important note: the endomembrane system does not include mitochondria, chloroplasts, or peroxisomes. Let’s take a closer look at the different parts of the endomembrane system and how they function in the shipping of proteins and lipids.

What are the parts of the endomembrane system?

Reading: Endomembrane System 1 Ribosomes. Ribosomes are made up of a large subunit (top) and a small subunit (bottom). 2 Endomembrane System. Membrane and secretory proteins are synthesized in the rough endoplasmic reticulum (RER). 3 The Endoplasmic Reticulum. 4 The Golgi Apparatus.
