Question
Which of the following proteins are embedded in the membrane?
- Membrane
- Essential
- Integral
- Peripheral
Hint:
The cell membrane consists of protein embedded in the lipid bilayer.
The correct answer is: Integral
- The integral proteins are the ones that are embedded in the membrane.
- The cells are surrounded by a membrane that protects them from the outer environment and acts as a barrier. This membrane is called the plasma membrane or cell membrane.
- It consists of a lipid bilayer and certain proteins are embedded in this lipid bilayer. They are known as integral proteins. Almost 70 to 80 percent of the proteins in the membrane are present in this form. Their main function is to transmit signals from one surface to the other.
The membrane proteins have two crucial roles, one structural and the other one is functional.
