The endoplasmic reticulum (ER) is a part of a transportation system of the eukaryotic cell, and has many other important functions such as protein folding. The word endoplasmic means “within the cytoplasm,” and reticulum is Latin for “little net”.

2024年12月13日 · 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 …

2021年1月15日 · The endoplasmic reticulum (ER) is a large organelle made of membranous sheets and tubules that begin near the nucleus and extend across the cell. The endoplasmic reticulum creates, packages, and secretes many of the products created by a cell.

2024年12月21日 · The endoplasmic reticulum (ER) is a vital cellular organelle, playing key roles in protein synthesis, lipid metabolism, and cellular signaling. Often referred to as the cell’s “factory” or “highway,” the ER’s unique structure and functions make it a key player in maintaining cellular homeostasis.

內质网 （英語： Endoplasmic reticulum, ER）是在 真核生物 细胞 中由膜围成的隧道系统，为细胞中的重要 细胞器。 实际上內质网是膜被摺疊成一個扁囊或細管狀構造，可分為粗糙內質網（Rough Endoplasmic Reticulum, RER）和光滑內質網一 …

The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.

All eucaryotic cells have an endoplasmic reticulum (ER). Its membrane typically constitutes more than half of the total membrane of an average animal cell (see Table 12-2). The ER is organized into a netlike labyrinth of branching tubules and flattened sacs extending throughout the …

The endoplasmic reticulum (ER) is a network of membrane-enclosed tubules and sacs (cisternae) that extends from the nuclear membrane throughout the cytoplasm (Figure 9.1). The entire endoplasmic reticulum is enclosed by a continuous membrane and is the largest organelle of most eukaryotic cells.

2023年4月1日 · The endoplasmic reticulum provides an ultrastructural skeletal framework to the cell and gives mechanical support to the colloidal cytoplasmic matrix. The exchange of molecules by the process of osmosis, diffusion and active transport occurs through the membranes of the endoplasmic reticulum.

ER with ribosomes attached is called rough endoplasmic reticulum and is involved in protein synthesis, production of new membrane, modification of newly formed proteins, and transport of these proteins and membrane to other locations within the cell.
