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.
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.

Active Transport
Passive Transport
it is the movement of materials through cell membrane using energy
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
Molecular Transport (in cells) is the movement of materials across a cell membrane. The two kinds of Molecular Transport used in organisms are Active Transport and Passive Transport. Active Transport- materials move across the plasma membrane with the use of energy (like Adenosine Triphosphate) Passive Transport- materials move accross the plasma membrane without the use of energy
The two energy carrier molecules used are NADH and FADH2. These molecules are produced during the citric acid cycle and deliver electrons to the electron transport chain, where they drive the production of ATP through oxidative phosphorylation.
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
Carrier-mediated transport can be either passive or active, depending on the type of carrier protein involved. Passive carrier-mediated transport allows molecules to move down their concentration gradient without requiring energy input, while active carrier-mediated transport moves molecules against their concentration gradient using energy from ATP or an electrochemical gradient.
