Phospholipids are important components of cell membranes because they
Options
- Acan be easily phosphorylated by ATP.
- Bcan transport sodium and potassium ions across the membrane.
- Cform a layered structure that can interface with water on two surfaces.
- Dform a lipid bilayer with their hydrophobic surface facing outward.
Correct answer
C. form a layered structure that can interface with water on two surfaces.
Step-by-step solution
The phospholipids are lipids with phosphate in their structure. It acts as a barrier and allows only selective passage of molecules and ions in and out o the cell. The characteristic feature of phospholipids is that they act as hydrophilic(head) and also as hydrophobic(tail) molecules and therefore are known as amphipathic as it forms bilayers in water.
