Question

What are the function of Rough endoplasmic Reticulam and smooth endoplasmic Reticulam​

Answer 1

Function of RER is protein synthesis

Function of SER is detoxification, biosynthesis of lipid, cholesterol, storage of calcium ion.

Explanation:

• Rough endoplasmic reticulum contain ribosome on their surface. therefore the surface of ER appeared as rough.
• we know that ribosome perform protein synthesis as this ER carry the ribosome, so function of RER is protein synthesis.
• Smooth endoplasmic reticulum lack ribosome so therefore it cannot perform protein synthesis.
• SER contain as enzymes that can make lipid soluble drug into water soluble, so that they can be easily expelled out of the body and this way they perform detoxification.
• The enzyme that synthesize the lipid component also present in SER that perform lipid biosynthesis.
• a smooth endoplasmic reticulum present in muscle is called sarcoplasmic reticulum that store calcium ions.
• calcium is require for muscle contraction.

Answer 2

1)The endoplasmic reticulum is one of the organelles that forms the endomembrane system.

2)It is further classified as rough endoplasmic reticulum and smooth endoplasmic reticulum​.

3)The rough endoplasmic reticulum has a rough surface due to the presence of ribosomes and they are mainly involved in protein synthesis.

4)Smooth endoplasmic reticulum does not have ribosomes attached to their surfaces and hence have a smooth surface. It is mainly helps in the synthesis of lipids and steroids.
