6 Questions
What is the main function of the cell membrane?
The main function of the cell membrane is to regulate the movement of substances in and out of the cell.
What are the components of the cell membrane?
The cell membrane is composed of phospholipids, proteins, and cholesterol.
How does the cell membrane maintain its structure and integrity?
The cell membrane maintains its structure and integrity through the arrangement of phospholipids in a bilayer and the presence of cholesterol molecules.
What is the role of cholesterol in the cell membrane?
Cholesterol helps regulate the fluidity and stability of the cell membrane.
What are lipid rafts and how do they contribute to cell membrane function?
Lipid rafts are specific regions of the cell membrane enriched in cholesterol and sphingolipids. They play a role in organizing signaling molecules and membrane proteins.
What is the significance of transmembrane proteins in the cell membrane?
Transmembrane proteins span across the lipid bilayer of the cell membrane and serve as channels, receptors, and transporters for various substances.
