Question

explain endoplasmic reticulum

Answer 1

Answer:

Endoplasmic Reticulum is a kind of organelle which we found in various eukaryotic cells.

In those eukaryotic cells, the endoplasmic reticulum works as manufacturing component of the system.

In short, the endoplasmic reticulum is the small network of membranes i.e. they are sac-like structures.

Endoplasmic Reticulum is referred as ER in short, where they are very useful in synthesis of steroid hormones affecting body.

➡️The endoplasmic reticulum (ER) is a type of organelle found in eukaryotic cells that forms an interconnected network of flattened, membrane-enclosed sacs or tube-like structures known as cisternae. The membranes of the ER are continuous with the outer nuclear membrane. The endoplasmic reticulum occurs in most types of eukaryotic cells, but is absent from red blood cells and spermatozoa.

➡️There are two types of ER: rough endoplasmic reticulum and smooth endoplasmic reticulum. The outer (cytosolic) face of the rough endoplasmic reticulum is studded with ribosomes that are the sites of protein synthesis. The rough endoplasmic reticulum is especially prominent in cells such as hepatocytes. The smooth endoplasmic reticulum lacks ribosomes and functions in lipid synthesis but not metabolism, the production of steroid hormones, and detoxification.[1] The smooth ER is especially abundant in mammalian liver and gonad cells.
