- Mechanical support: E.R. will give mechanical support to cytoplasm. Hence it is called cytoskeleton.
- Intracellular transport: E.R. functions as circulatory system of the cell. It transport substance from one place to another place, in the cell it is called intracellular transport.
- Protein synthesis: ER. will provide surface for the attachment of ribosomes. These ribosomes will synthesise the proteins.
- Synthesis of lipoproteins: Smooth E.R. will synthesise lipids. In the Golgi complex the glycerides get associated with proteins produced by the E.R. Thus complex lipoproteins are formed.
- Detoxification: Smooth E.R. will detoxify internal, or external toxins. If toxins are more in the body more smooth E.R. will be produced.
- A.T.P. Synthesis: E.R. membranes are the sites of A.T.P, synthesis in the cell.
- Formation of other membranes: In the cell E.R. gives rise to.
a) Cisternae of Golgi apparatus.
b) Outer membrane of nucleus.
- Impulse conduction: In the muscle sarcoplasmic eticulum will release calcium which is responsible for the muscle action In 1926 "Porter" stated that E.R. membrane shows ionic grandients, and electric potential.
- The outer membrane of the nucleus will give buds. They unite to form annulate lamellae.
- Annulate lamellae will give rough E.R.
- From smooth E.R. golgi will form.
- Vesicles will give plasma lemma.
- According to GERL system Golgi will give rise to primary lysosomes. Thus there is an interrelationship among the membrane systems.
