Question

define endomembrane system​

Answer 1

$\huge\mathfrak\pink{Answer}$

$\sf\implies$The endomembrane system is a system of membranous components.

$\sf\implies$It includes the membranes of nucleus, endoplasmic reticulum, Golgi apparatus, lysosomes, endosomes, vesicles, and the cell membrane.

Answer 2

Some points on the endomembrane system are :-

The endoplasmic reticulum(ER) is the organelle that consists of irregular network of tubular double Membrane which are continuous and is connected with the plasma Membrane and nuclear Membrane.

The ER is divided into two categories :

1. Smooth ER:- It is called smooth endoplasmic reticulum when no ribosomes are attached to the membrane.

2. Rough ER:- It is called rough endoplasmic reticulum when ribosomes are attached to it's Membrane.

Functions :-

=>Smooth ER helps in the synthesis of lipid,glycogen, and steroid hormones.

=>Rough ER is included in the synthesis of proteins.
