Endoplasmic reticulum - Wikipedia
网页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. It is a type of organelle made up of two subunits – rough endoplasmic reticulum (RER), and smooth endoplasmic reticulum (SER).
Endoplasmic Reticulum - Definition, Function and Structure
网页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 …
Endoplasmic Reticulum - Structure and its Functions - BYJU'S
网页Endoplasmic Reticulum is a network of membranous tubules present within the cytoplasm of a eukaryotic cell. There are two regions and they differ in both structure and its function.
Section 5.5B: The Endoplasmic Reticulum - Biology LibreTexts
网页2 天之前 · 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 (Figure Section5.5B. 33 S e c t i o n 5.5 B. 33). The ER functions to: provide a surface area for protein and lipid synthesis; form a pathway for ...

网页4 天之前 · The endoplasmic reticulum (ER) is a system of membranous cisternae (flattened sacs) extending throughout the cytoplasm. Often it constitutes more than half of the total membrane in the cell.
5.9: The Endoplasmic Reticulum - Biology LibreTexts
网页The endoplasmic reticulum (ER) is a series of interconnected membranous tubules that collectively modify proteins and synthesize lipids. However, these two functions are performed in separate areas of the endoplasmic reticulum: the rough endoplasmic reticulum and the smooth endoplasmic reticulum, respectively.
The Endoplasmic Reticulum - The Cell - NCBI Bookshelf
网页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.
The Endoplasmic Reticulum - Molecular Biology of the Cell
网页The ribosome that is synthesizing the protein is directly attached to the ER membrane. These membrane-bound ribosomes coat the surface of the ER, creating regions termed rough endoplasmic reticulum, or rough ER (Figure 12-36A).
