Cell Transport

Front

What is Active Transport?

Back

Active Transport is the movement of solutes against the concentration gradient, requiring energy (ATP).

Front

What is Passive Transport?

Back

Passive Transport is the movement of particles from high to low concentration without the use of energy.

Front

What is Osmosis?

Back

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

Front

Is Osmosis a form of Active or Passive Transport?

Back

Osmosis is a form of Passive Transport.

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells.

Front

What does 'Concentration Gradient' mean?

Back

A concentration gradient refers to the difference in the concentration of a substance between two areas.

Front

What is the role of a cell membrane in transport?

Back

The cell membrane regulates the movement of substances in and out of the cell.

Front

What is facilitated diffusion?

Back

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

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of solutes, while osmosis specifically refers to the movement of water.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain substances to pass while blocking others.
