Active transport proteins utilize ATP to move substances against concentration gradients, unlike facilitated diffusion proteins that do not require ATP.
Proteins for active transport require energy in the form of ATP to move substances against a concentration gradient, creating specific solute gradients. Various types of transporters, such as uniporters, symporters, and antiporters, are involved in this process. These proteins are distinct from those used in facilitated diffusion, as they necessitate energy input to function effectively.
