endóplasmatískum
Endóplasmatískum, more commonly known as the endoplasmic reticulum or ER, is a complex network of membranes found within eukaryotic cells. It is composed of flattened sacs called cisternae and interconnected tubules. The ER plays a crucial role in the synthesis, modification, and transport of proteins and lipids. It is continuous with the outer nuclear membrane and extends throughout the cytoplasm of the cell.
There are two distinct regions of the endoplasmic reticulum: the rough endoplasmic reticulum (RER) and the smooth
The SER lacks ribosomes and appears "smooth." Its functions are more diverse and include lipid synthesis, detoxification
