32 Phospholipids have polar and nonpolar ends. Why is this important for their roles in cells? They help to keep water out of the cell. They help proteins function inside the cell. They regulate what can cross the cell membrane. They allow proteins to be embedded in the cell membrane.

Describe the amphipathic nature of phospholipids. Why is this important for the role that these molecules play in our cell membranes
Madhur L.
Why properties of phospholipids drive the formation of a phospholipid bilayer? How does it form? What makes the cell membrane mosaic? What are the components that make it mosaic? Can components of the cell membrane diffuse laterally? flip from one side of the bilayer to the other? Explain why or why not.
