Review #4: The Cell Membrane and Cell Transport

Front

Hydrophilic means...

Back

water-loving

Front

Which type of passive transport uses proteins to help molecules pass through the membrane?

Back

Facilitated diffusion

Front

What happens to a cell in an isotonic solution?

Back

Water entering and exiting the cell is equal

Front

What is diffusion?

Back

when molecules move from a high concentration to a low concentration.

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 main components of the cell membrane?

Back

Phospholipids, proteins, carbohydrates, and cholesterol.

Front

What does it mean if a solution is hypertonic?

Back

It has a higher concentration of solutes compared to the cell.

Front

What is osmosis?

Back

The movement of water across a selectively permeable membrane.

Front

What is the role of proteins in the cell membrane?

Back

To facilitate transport and communication across the membrane.

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain molecules to pass while blocking others.
