Which one of the following is not a constituent of the cell membrane?
Which one of the following is not a constituent of the cell membrane?
The correct option is D Prolin
The correct answer is option D.
Explanation of correct answer:
Cell membrane or plasma membrane:
It is a type of biological membrane which separates the interior from the outside environment of the cell and protects it. It transports the material across the selectively semi-permeable membrane.
Proline:
- Proline is an amino acid that is generally not a constituent of any biological membrane.
- It works as a building block for protein.
Explanation for Incorrect answer:
Option A:
Cholesterol is present in the cell membrane, stabilizing them at high temperatures.
Option B:
Glycolipids: It is found in the outer leaflet of the cell membrane.
Option C:
Phospholipid: The lipid component of the membrane is mainly composed of phosphoglycerides called Phospholipids.
Final Answer: Proline is not a constituent of the cell membrane.
