Q
The Fundamental Unit of Life

Question:

Where do the lipids and proteins constituting the cell membrane get synthesised?

Answer:

The endoplasmic reticulum is a series of membranous networks in the cytoplasm of eukaryotic cells. One end of the endoplasmic reticulum is connected to the nuclear membrane and the other end is connected to the plasma membrane. Most eukaryotic cells have two types of the endoplasmic reticulum:

1. Rough endoplasmic reticulum (RER) with ribosomes attached on its surface which is responsible for protein synthesis.

2. Smooth endoplasmic reticulum (SER) plays an important role in the synthesis of lipids and fats.
