Cellular Transport

Front

What happens to a cell in a hypotonic solution?

Back

The cell will swell due to the influx of water.

Front

What does active transport require?

Back

Active transport requires energy to move molecules against their concentration gradient.

Front

What is the process called when molecules move from an area of high concentration to an area of low concentration without energy?

Back

This process is called passive transport.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy, while passive transport does not.

Front

What is an example of active transport?

Back

An example of active transport is the sodium-potassium pump.

Front

What is an example of passive transport?

Back

An example of passive transport is the movement of oxygen into cells.

Front

What is the role of energy in cellular transport?

Back

Energy is required for active transport to move substances against their concentration gradient.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move molecules across the membrane.
