Front

What are phospholipids composed of?

Back

A hydrophilic head and two hydrophobic tails.

Front

What is the primary function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

Define selective permeability in the context of cell membranes.

Back

The ability of the cell membrane to allow certain substances to pass while blocking others.

Front

What role do carbohydrates play in the cell membrane?

Back

They are involved in cell recognition and signaling.

Front

What is the fluid mosaic model?

Back

A model that describes the structure of the cell membrane as a mosaic of various components that move fluidly.
