Question
A plasma membrane shows fluid behaviour _____
- Due to mosaic of proteins and lipid
- Due to presence of fluid protein
- Due to mosaic of fat and sucrose
- Due to sandwich of protein between lipid layers
Hint:
A plasma membrane is composed of certain biochemical compounds that provide fluidity to the cell.
The correct answer is: Due to mosaic of proteins and lipid
- A plasma membrane shows fluid behavior due to the mosaic of lipids and proteins.
- The plasma membrane is a membrane that surrounds the protoplasm or cytoplasm of the cell. It protects the inner matter of the cell from the external environment.
- It is composed of a lipid bilayer with some specific integral proteins embedded in its structure. This gives the cell membrane its fluidity, and some rigidity. The lipid layer is mainly composed of cholesterol which is well known for giving fluidity to the cell.
The plasma membrane is semi-permeable in nature. It allows only certain molecules to enter the cell.
