Front

What is the primary function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What are the two main types of proteins found in the cell membrane?

Back

Integral proteins and peripheral proteins.

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 freely.

Front

What is the hydrophobic region of the cell membrane?

Back

The fatty acid tails of phospholipids that repel water.
