Question

explain endoplasmic reticulum in detail?

Answer 1

hey mate here is your answer.....


''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 endoplasmic reticulum: rough (granular) and smooth (agranular). 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 manufacture and metabolism, the production of steroid hormones, and detoxification.[1] The smooth ER is especially abundant in mammalian liver and gonad cells.''

======================================
✔ENDOPLASMIC RECTUCULUM is a type of organelle made of membranous sheets and tubules that began near the nucleus and extend across the cells ...

FUNCTIONS OF ENDOPLASMIC RECTICULUM


➡️It is mainly responsible for the transportation of proteins and other carbohydrates to another organelle, which includes lysosomes, Golgi apparatus, plasma membrane, etc.
➡️They play a vital role in the formation of the skeletal framework.
➡️They provide the increased surface area for cellular reactions.
➡️They help in the formation of nuclear membrane during cell division.
➡️They play a vital role in the synthesis of proteins, lipids, glycogen and other steroids like cholesterol, progesterone, testosterone, etc.
