Quelle est la fonction du reticulum endoplasmique lisse?

Quelle est la fonction du réticulum endoplasmique lisse?

Rôle du réticulum endoplasmique Il participe au bon repliement des protéines qui viennent d’être synthétisées. Le réticulum endoplasmique lisse participe pour sa part au métabolisme cellulaire, en synthétisant des lipides et en stockant le calcium.

Qu’est-ce que les lysosomes?

Les lysosomes sont des organites cellulaires moins connus que les mitochondries ou le noyau mais qui néanmoins jouent un rôle essentiel par leur contenu en enzymes hydrolytiques dans la dégradation des molécules et des organites intracellulaires (autophagie) et dans la destruction des molécules ingérées par la cellule …

What is an example of endoplasmic reticulum?

The endoplasmic reticulum is defined as a series of folded membranes in the cells which are associated with protein synthesis, storage and the movement of cellular materials. An example of the endoplasmic reticulum is the place that steroids are stored in the cells for later use.

What is the importance of endoplasmic reticulum?

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).

What is endoplasmic reticulum best described as?

a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.

What is the job of smooth endoplasmic reticulum?

The duties of the smooth endoplasmic reticulum vary depending on the type of cell, but one of the most important functions of this cellular structure is the synthesis of phospholipids and cholesterol.
