Question
______ are the components of cell membrane.
- Protein and vitamin
- Lipid and riboflavin
- Protein and lipid
- Carbohydrate and protein
Hint:
The cell membrane is made up of biochemical components.
The correct answer is: Protein and lipid
- The components of the cell membrane are protein and lipids.
- The plasma membrane or cell membrane is a structure present in the cell that helps to protect the cell from the outer environment and also ensures the movement of molecules through it.
- It is made up of a lipid bilayer, that is, two layers of lipid joined together. This bilayer also consists of protein molecule embedded in its structure. These protein molecules are called integral proteins.
- The lipid portion provides fluidity to the cell and the protein ensures that the molecules are able to cross the cell membrane. As the cell membrane is selectively permeable, only certain molecules can pass through it.
The cell membrane also consists of carbohydrates in its structure. They are known to help in cell-to-cell identification and interaction process.
