endoplazmatickém

Endoplazmatickém refers to the endoplasmic reticulum, a complex network of membranes found throughout the cytoplasm of eukaryotic cells. It is involved in protein and lipid synthesis and modification, as well as calcium storage and transport. The endoplasmic reticulum is composed of two interconnected regions: the rough endoplasmic reticulum (RER) and the smooth endoplasmic reticulum (SER). The RER is studded with ribosomes, giving it a "rough" appearance, and is primarily involved in the synthesis and folding of proteins destined for secretion or insertion into membranes. The SER lacks ribosomes and is involved in lipid synthesis, detoxification of drugs and poisons, and calcium storage. The endoplasmic reticulum plays a crucial role in maintaining cellular homeostasis and is essential for cell function.
