Question:
Differentiate between rough and smooth endoplasmic recticulum. How is endoplasmic reticulum important for membrane biosynthesis?
Solution:
(b) Membrane Biosynthesis : Both the types of E.R. take part in membrane biosynthesis. Rough endoplasmic reticulum synthesises proteins which are passed over to Golgi apparatus for glycolisation. Smooth endoplasmic reticulum forms lipids over its surface. They are also transported to Golgi apparatus. Golgi apparatus builds membrane with the help of lipids and proteins.
