How would you describe the structure of the Endoplasmic Reticulum?

Question

Ruby Armstrong · Accepted Answer

Structure of the endoplasmic reticulum is a network of membranes with either ribosomes present or absent.

The structure of the endoplasmic reticulum is a network of membranes that are interwoven to form the cytoskeleton. The lumen is enclosed by the phospholipid nature of the membrane, and these spaces are continuous with the perinuclear space. The endoplasmic reticulums are classified into two types based on the presence or absence of ribosomes: 1. Rough endoplasmic reticulum, which contains ribosomes and aids in protein synthesis. 2. Smooth endoplasmic reticulum, which lacks ribosomes.

undefined The membrane-bound organelle known as the endoplasmic reticulum (ER) is present in eukaryotic cells and is made up of a network of flattened sacs and tubules known as cisternae. Rough ER and smooth ER are the two types of ER; the former has ribosomes studded on its surface, giving it a rough appearance, while the latter does not. The ER is essential for calcium ion storage, lipid metabolism, and protein synthesis.
