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.
cell membrane
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.
cell membrane
Carrier proteins can be involved in passive transport.
Carrier proteins are sometimes used during passive transport.
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
