Cellular Transport

Front

What happens to a cell in a hypotonic solution?

Back

Water will go INTO the cell.

Front

What is diffusion?

Back

The movement of particles from high to low concentration.

Front

Which type of transport does NOT use proteins?

Back

Osmosis.

Front

What is a hypertonic solution?

Back

A solution that has a greater concentration on the outside of the cell than inside.

Front

What is passive transport?

Back

The movement of molecules from high to low concentration without the use of energy.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is an isotonic solution?

Back

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

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a cell membrane via protein channels.

Front

What role do proteins play in cellular transport?

Back

Proteins can act as channels or pumps to help move substances across the cell membrane.
