2024年12月13日 · Endoplasmic reticulum, 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.

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21日 · The endoplasmic reticulum or ER is a network of membranes extending from the nuclear envelope that acts as the factory and highway of the cell. It exists in two types: rough ER (protein synthesis) and smooth ER (lipid synthesis and detoxification).

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.

2025年1月22日 · The endoplasmic reticulum or ER is a maze of parallel membranous tubules and flattened sacs surrounding the nucleus that connects with the nuclear membrane and runs throughout the cytoplasm. ER with ribosomes attached is called rough endoplasmic reticulum and is involved in protein synthesis, production of new membrane, modification of newly ...

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.

The endoplasmic reticulum is the cell organelle that originates from the cell’s nuclear envelope, synthesizes protein, and transports the proteins for cellular metabolism. Depending on the cell, the endoplasmic reticulum can occupy 50% of the cell volume.

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.

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.

2024年7月19日 · The endoplasmic reticulum is a network of membranous tubules and flattened sacs that extend throughout the cytoplasm. This extensive network is divided into two distinct regions: the rough ER and the smooth ER, each with unique structural features and functions.
