Cell membrane:
- Cytoplasm of cells is enclosed in a phospholipid bilayer called cell membrane or plasma membrane.
- The formation of plasma membrane is called biogenesis of cell membrane.
Biogenesis of cell membrane:
- Biogenesis of cell membrane involves the synthesis of proteins and lipids.
- Nucleus is the control centre of the cell and it directs the synthesis of the cell membrane.
- Ribosomes are tiny granular particles which act as the site of protein synthesis.
- Ribosomes are found attached to the endoplasmic reticulum and this type of ER is called rough endoplasmic reticulum.
- Rough endoplasmic reticulum help in the transport of synthesised protein.
- The endoplasmic reticulum which is devoid of ribosomes is called smooth endoplasmic reticulum.
- Smooth endoplasmic reticulum is concerned with the synthesis of phospholipids which is the major component of plasma membrane.
- Golgi bodies are membrane-bound spaces located near the endoplasmic reticulum.
- The synthesised proteins and lipids from endoplasmic reticulum are transported to the golgi apparatus.
- Golgi apparatus help in the packaging of formed proteins and lipids.
- Vesicles are membrane-bound bodies of golgi apparatus.
- Vesicles help in the transport of proteins and lipids into or out of the cell.
