HB BIO CH 7 Passive and Active Transport

Front

What is the difference in the concentration of solutes between the inside and outside of the cell called?

Back

Concentration gradient.

Front

What happens to red blood cells (RBCs) when they are exposed to a hypotonic solution?

Back

They swell and may burst due to water entering the cells.

Front

In passive transport, molecules move from an area of __________ concentration to an area of __________ concentration.

Back

High concentration to low concentration.

Front

What type of solution are cells in when they are in an isotonic environment?

Back

Isotonic solution means the concentration of solutes is equal inside and outside the cell.

Front

In which type of solution will water move into a cell?

Back

Hypotonic solution.

Front

What is diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of 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 is an isotonic solution?

Back

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