Diffusion requires no energy as it follows the electrochemical gradient. Active transport requires energy (ATP), as it works against the electrochemical gradient.
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
diffusion, facilitated diffusion, and osmosis
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
Facilitated diffusion occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side. This type of transport does not require energy and relies on the concentration gradient to move molecules across the membrane.
Diffusion-the random movement of molecules from an area of higher concentration to an area of lower concentration.Osmosis-the diffusion of water across a semipermeable membrane.
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).

Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.
Osmosis, diffusion, facilitated diffusion, active transport
Things can enter the cell through various processes, such as osmosis, diffusion and active transport. Passive transport (diffusion/osmosis) occurs because of a difference in concentration across the membrane.

diffusion, facilitated diffusion, and osmosis
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
Facilitated diffusion is a type of passive transport where specific molecules are transported across the cell membrane with the help of transport proteins. Unlike simple diffusion, facilitated diffusion requires the presence of these proteins to facilitate the movement of molecules across the membrane.
Facilitated diffusion (or facilitated transport) is a form of passive transport that is facilitated by transport proteins. Most often it is used to transport polarized molecules (such as glucose and amino acids) across the cell membrane.
