What is Active Transport?

Back

The movement of molecules across a cell membrane using energy, usually against a concentration gradient.

Front

What is Osmosis?

The diffusion of water across a selectively permeable membrane.

Front

What is the role of ATP in Active Transport?

Back

ATP provides the energy required for the transport of molecules against their concentration gradient.

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.
