The process that requires energy to move molecules across the cell membrane is called active transport. Unlike passive transport, which relies on concentration gradients, active transport uses cellular energy, typically in the form of ATP, to move molecules against their concentration gradient. This enables cells to maintain necessary concentrations of ions and nutrients despite external conditions. Examples include the sodium-potassium pump and proton pumps.
Active transport requires energy to move molecules across the cell membrane against their concentration gradient. This process is carried out by specific proteins called pumps that utilize cellular energy in the form of ATP to transport molecules.
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
Active transport. This process requires energy, usually in the form of ATP, to move molecules or ions against their concentration gradient across a cell membrane.
when proteins help molecules move across the membrane, it it called Facilitated Diffusion

Diffusion of molecules across the cell membrane is actually a passive process, not active. Active transport, which requires energy in the form of ATP, is a more complex process as it moves molecules against their concentration gradient.

The movement of molecules across a membrane down the concentration gradient is a passive process.
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.

Active transport is the process by which a cell uses energy to move molecules or ions across a cell membrane against their concentration gradient. This process requires the use of ATP energy to pump substances from an area of low concentration to an area of high concentration.
You are describing active diffusion.
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
Facilitated diffusion across a biological membrane requires the presence of specific protein channels or carriers to assist in the movement of molecules from an area of high concentration to an area of low concentration. The process does not require energy input from the cell and relies on the concentration gradient to drive the movement of molecules.
