颗粒状和农业内质网之间的差异|比较类似术语之间的差异

这关键区别between granular and agranular endoplasmic reticulum is thatgranular endoplasmic reticulum has核糖体在表面上方，而肉眼内质网状网状核糖体在表面上没有核糖体。

内质网（ER）是一系列扁平的囊和一系列的小管网络cytoplasm真核细胞。ER是一个重要的细胞器，参与蛋白质的合成，折叠，修饰和运输。此外，ER在钙储存，碳水化合物代谢以及脂质合成和代谢中起关键作用。基于核糖体的存在或存在，有两种类型的ER。它们是粗糙的或颗粒状的，光滑的或植物的。颗粒状ER在表面上有核糖体，使其看起来粗糙。植物ER在表面上没有核糖体，使其具有光滑的外观。许多细胞都有两种类型的ER。

什么是颗粒状内质网？

颗粒状内质网是两种类型的ER之一，表面上有核糖体。Rough ER是粒状ER的另一个名称，因为它的外观粗糙。颗粒状ER在诸如肝细胞等细胞中丰富，它们积极合成酶等蛋白质。颗粒状ER与蛋白质合成有关。蛋白质折叠是粒状ER的另一个主要功能。此外，颗粒状ER可以进行蛋白质分类。

什么是农业内质网？

Agranular endoplasmic reticulum is the type of ER that do not have ribosomes over the surface or embedded within it. Hence, it has a smooth appearance and occurs mainly in a tubular form.Smooth ER是Agranular ER的另一个名称。植物ER参与细胞所需的各种物质的生产，例如必需脂质（磷脂和胆固醇）和类固醇激素等。此外，它将粗糙ER的产物传输到其他细胞器，尤其是高尔基体。除此之外，农业ER还负责碳水化合物的代谢。植物ER还存储并释放钙离子。

颗粒状和肉眼内质网有什么区别？

Granular ER is the type of ER that has ribosomes on it while agranular ER is the type of ER that does not have ribosomes on it. Thus, this is the key difference between granular and agranular endoplasmic reticulum. Moreover, granular ER has a rough appearance while agranular ER has a smooth appearance. Besides, granular ER is responsible for protein synthesis, protein folding and protein sorting. In contrast, agranular ER helps to synthesize and concentrate various substances such as phospholipids, etc., needed by the cell. It is also responsible for carbohydrate metabolism, storing and releasing calcium ions, etc. So, this is the functional difference between granular and agranular endoplasmic reticulum.

颗粒状ER在积极合成蛋白（例如酶和腺体）的细胞中最常见，而granular ER在涉及类固醇或脂质合成，碳水化合物代谢，电解质排泄，脉冲传导，脉冲传导和生产的细胞中最常见。

摘要 - 颗粒状与农业内质网

内质网是一个管状的中介银行网络ranes found within the cytoplasm of the eukaryotic cell. ER can be either granular or agranular based on the presence and absence of ribosomes over the surface. The key difference between granular and agranular endoplasmic reticulum is that the granular ER has ribosomes attached to it while agranular ER lacks ribosomes. Besides, granular ER has a rough appearance while agranular ER has a smooth appearance. Granular ER carries out protein synthesis, folding, quality control and protein sorting. Agranular ER carries out the synthesis of various lipids, steroid hormones, etc. needed by the cell. Moreover, it carries out carbohydrate metabolism and storing and releasing calcium ions in the cell. So, this summarizes the difference between granular and agranular endoplasmic reticulum.
