Question

What is membrane biogenesis? How is plasma membrane formed during this process?

July 13, 2024

Answer

The process of plasma membrane formation is called membrane biogenesis. Following organelles are involved in this process:

The proteins and lipids are first synthesised in rough endoplasmic reticulum and the smooth endoplasmic reticulum, respectively. These are then transported to the Golgi complex for their modification. After modification, these are transported to the cell surface through vesicles which bud off from Golgi complex to fuse with cell membrane and form a part of the membrane.
