Cell Transport and Tonicity Review

Front

What are the three main components of the cell membrane?

Back

Lipids, Proteins, Carbohydrates

Front

What happens to a cell placed in a hypertonic solution?

Back

The cell would shrink.

Front

What does 'high concentration area' mean?

Back

Tightly packed together.

Front

What type of solution is a cell in if it is placed in a hypertonic environment?

Back

Hypertonic.

Front

If a cell is in a hypertonic solution, what is the effect on the cell?

Back

The cell will lose water and shrink.

Front

Define isotonic solution.

Back

A solution where the concentration of solutes is equal inside and outside the cell.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell.

Front

What occurs to a cell in a hypotonic solution?

Back

The cell will gain water and may burst.

Front

Explain the term 'osmosis'.

Back

The movement of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What role do proteins play in the cell membrane?

Back

Proteins assist in transport, act as receptors, and provide structural support.
