i dont not know so someone answer it soon please:(
cell membrane
Energy, versus passive in which energy is not used.
In active transport, proteins like pumps (such as Na+/K+ ATPase) are commonly used to move molecules against their concentration gradient, requiring energy in the form of ATP. Passive transport commonly involves proteins like ion channels and carrier proteins that facilitate the movement of molecules down their concentration gradient without requiring energy input.
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.
Proteins are major substances involved in active transport within cells. Examples include ion pumps like Na+/K+ ATPase and transporters like glucose transporters. ATP provides the energy needed for these proteins to actively transport molecules across the cell membrane.

Transport proteins such as ion channels and carrier proteins are used in both active and passive transport processes. Ion channels move ions down their concentration gradient through passive transport, while carrier proteins can facilitate passive transport by allowing molecules to move along their concentration gradient, or active transport by requiring energy to transport molecules against their concentration gradient.

ATP is being used to move molecules out of the cell by providing energy to transport proteins in the cell membrane. These proteins use ATP to change shape, allowing them to pump or transport molecules against their concentration gradient. This process is called active transport.
Carrier proteins are sometimes used during passive transport.
Carrier proteins involved in active transport are often referred to as "pumps" because they actively move molecules against their concentration gradient, requiring energy input, similar to how a pump requires energy to move water against gravity. These proteins undergo conformational changes to bind and release molecules, allowing them to transport substances across the cell membrane.
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.
