Because they remove or bring in a chemical against the gradient.
Carrier proteins in active transport function as "pumps" that moves substance against their concentration gradient because of this reason that's why they are often called membrane pumps.
b/c
Carrier proteins of the cell membrane transport substances down their concentration gradient out of or into the cell by facilitated diffusion and active transport.
cellular transport nop, is passive transport
Active transport involves carrier proteins. Carrier proteins bind themselves to particles and transport them to highly concentrated areas within a cell.Facilitated diffusion and active transport require carrier proteins.
Active
carrier proteins transport glucose into a muscle cell
Carrier proteins of the cell membrane transport substances down their concentration gradient out of or into the cell by facilitated diffusion and active transport.
Molecules are moved through the cell membrane by active transport.
They help transfer substances from the outside of the cell membrane to the inside.
A carrier protein (as opposed to a channel protein). An example of a carrier protein is the Na+/K+ pump.
Actually, bilipid "heads" form the layers of the membrane, but there are carrier proteins that transport objects into and out of the cells. These carrier proteins use either active or passive transport to get objects across the membrane. Active transport uses energy, while passive transport doesn't need to use energy to get items across. Hope this helps!!!

Carrier Proteins
i dont not know so someone answer it soon please:(
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
