Question

differentiate between Rough Endoplasmic reticulum (RER) and Smooth Endoplasmic Reticulum (SER).2points

Answer 1

hey mate ✨✨✨✨✨

Smooth Endoplasmic reticulum(SER)-Have smooth surface & absence of ribosome on its surface,it is responsible for lipid metabolism(both anabolism & catabolism) steroid,fatty acid & phospholipid synthesis;Glycogenolysis(degradation of glycogen)& Drug detoxification(by the help of cytochrome P-450)or we can say SER is present where these component are active.

Rough endoplasmic reticulum(RER)-Have rough surface due to presence of ribosome,found where cells are engaged in protein synthesis(as well as membrane protein and glycoprotein);RER was earlier known as ergastroplasm.

I hope it will help you ✨✌️✨✌️✨✌️✨

Answer 2

ROUGH ENDOPLASMIC RETICULUM ( RER )

1) Rough endoplasmic reticulum is studded with ribosomes .

2) These are mainly composed of Cisternae .

SMOOTH ENDOPLASMIC RETICULUM ( SER )

1) Smooth endoplasmic reticulum is not associated with ribosomes .

2) These are mainly composed of tubules .
