Class 11 endomembrane system- The endomembrane system is a complex cellular structure found in eukaryotic cells, which includes various membrane-bound organelles that work together to perform different functions within the cell. These organelles are interconnected, and they play crucial roles in processes such as protein synthesis, modification, and transport, as well as lipid synthesis and degradation. The major components of the endomembrane system include the endoplasmic reticulum (ER), Golgi apparatus, lysosomes, vesicles, and the nuclear envelope.

1. Endoplasmic Reticulum (ER):
   • The endoplasmic reticulum is a network of membranes that comes in two forms: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER).
   • The rough endoplasmic reticulum is studded with ribosomes on its cytoplasmic surface, where protein synthesis occurs.
   • The smooth endoplasmic reticulum lacks ribosomes and is involved in lipid synthesis, detoxification, and storage of calcium ions.
2. Golgi Apparatus:
   • The Golgi apparatus is responsible for receiving, modifying, sorting, and shipping proteins and lipids from the endoplasmic reticulum to various destinations within the cell or for secretion outside the cell.
   • It consists of a series of flattened membrane sacs called cisternae.
3. Lysosomes:
   • Lysosomes are membrane-bound vesicles containing digestive enzymes.
   • They play a role in intracellular digestion, breaking down cellular waste, and recycling cellular components.
4. Vesicles:
   • Vesicles are small membrane-bound sacs that transport materials within the cell.
   • They can move substances between the different components of the endomembrane system or transport materials to and from the cell surface.
5. Nuclear Envelope:
   • The nuclear envelope surrounds the nucleus of the cell, separating it from the cytoplasm.
   • It consists of a double membrane with nuclear pores that regulate the passage of materials between the nucleus and the cytoplasm.

The endomembrane system works in a coordinated manner to ensure the proper synthesis, modification, and transport of proteins and lipids within the cell. It plays a crucial role in maintaining cellular homeostasis and supporting various cellular functions.
