The correct answer is: A. Lipids are maximum.
Lipids are the main component of the cell membrane, making up about 70% of its mass. Proteins make up about 20% of the cell membrane, and carbohydrates make up about 10%.
Lipids are important for the cell membrane because they provide a barrier that protects the cell from the environment. They also help to regulate the movement of molecules in and out of the cell.
Proteins are important for the cell membrane because they help to control the movement of molecules in and out of the cell. They also help to provide structural support for the cell membrane.
Carbohydrates are important for the cell membrane because they help to identify the cell to other cells. They also help to protect the cell from the environment.
All three of these components are important for the cell membrane, but lipids are the most abundant.
