Question

explain the structure and function of endoplasmic reciculum​

Answer 1

Answer:

The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.

Answer 2

Answer:

Structure of the Endoplasmic Retivulum:-

This is the structure of Endoplasmic Reticulum which is shown in the picture.

Function of the Endoplasmic Reticulum:-

The Endoplasmic Reticulum (ER) is a large network of membrane-bound tubes and sheets. The ER membrane is similar in structure to the plasma membrane. Endoplasmic Reticulum may have some granule like structure on their surface which are called ribosomes, such parts are called Rough Endoplasmic Reticulum (RER). Areas/sections that do not have ribosomes on them are Smooth Endoplasmic Reticulum (SER). Rough Endoplasmic Reticulum is site of protein manufacture. The SER helps in the manufacture of fat molecules, or lipids, important for cell function. The manufactured proteins and lipids are then sent to various places in the cell depending on need. Some of these proteins and lipids help in building the cell membrane.
