Which of the following transport processes requires the energy of ATP to move substances across the plasma membrane?

A) Diffusion
B) Osmosis
C) Facilitated diffusion
D) Active transport
E) Filtration

ATP

Adenosine triphosphate, a molecule that stores and transfers energy within cells, facilitating many biological processes.

Active Transport

The movement of molecules across a cell membrane from a region of lower concentration to higher concentration, requiring energy.

Facilitated Diffusion

A process of passive transport, as opposed to active transport, where molecules move across a membrane with the assistance of transport proteins, without energy expenditure.
