Question
What is ‘X’ in the diagram given below?
- Vitamin
- Protein
- Carbohydrate
- Lipid
Hint:
The figure shown here represents the cell membrane.
The correct answer is: Protein
- The X mentioned in the diagram is a protein.
- The diagram mentioned here is of the plasma membrane. The plasma membrane refers to the layer that surrounds the cell and protects its inner matter from the outer environment. It maintains stability inside the cell. It is composed of a lipid bilayer with proteins embedded in it,
- The lipid bilayer consists of integral proteins and transport proteins present in it. The transport proteins are responsible for carrying the molecules across the membrane in case of active passage or facilitated diffusion.
The peripheral membrane protein provides mechanical support to the membrane.
