Yes, active transport requires carrier proteins in order to function. These require ATP to carry things in and out of the cell.

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.

Proteins used in active transport are called carrier proteins.

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.

Carrier proteins of the cell membrane transport substances down their concentration gradient out of or into the cell by facilitated diffusion and active transport.

no, but active transport on the other hand, does require transport proteins to transport the large molecules into the cell.

Carrier proteins can use active or passive transport depending on what type of carrier protein it is (meaning what the protein transports). The form of passive transport that they use is facilitated diffusion. An example of active transport is the Sodium Potassium pump. Active transport requires ATP. Facilitated diffusion is used to transport polar molecules and ions that cannot directly cross the cell membrane. Facilitated diffusion doesn't require energy.

Nope. Facilitated diffusion is a passive transport. It uses carrier proteins, but doesn't require any energy.

facillitated diffusion and active transport

The carrier proteins that serve in active transport are often called cell membrane "pumps" because they move substances up their concentration gradients.

Yes, active transport involves proteins transporting substances against their concentration gradient with the help of ATP.

facilitated diffusion and active transport

facilitated diffusion does not require energy, as it travels from a higher concentration gradient to a lower one(passive transport). Pumps do require energy to function(Active transport). This energy needed is ATP.

No; they are involved in endocytosis and active transport.

Active transport does require a carrier protein. Each protein is specific to one particular molecule.

Molecules are moved through the cell membrane by active transport.

Carrier Proteins. Some don't require ATP (Facillitated transport) and some do require ATP (Active transport) to change shape.

Carrier Proteins. Some don't require ATP (Facillitated transport) and some do require ATP (Active transport) to change shape.

Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.

The carrier molecules used in active transport across cell membranes are carrier proteins. Each carrier protein is designed to recognize only one substance.

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.
