Active transport moves substances against the concentration gradient.
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
Active transport requires ATP and passive transport does not. Active transport goes against the concentration gradient and passive transport goes with the concentration gradient and includes osmosis, diffusion and facilitated diffusion.
what is the difference between a diffusion and a dilution
Diffusion requires no energy as it follows the electrochemical gradient. Active transport requires energy (ATP), as it works against the electrochemical gradient.
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.
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.
Diffusion is the movement of molecules from areas of high concentration to areas of low concentration and active transport is the movement of molecules from an area of low concentration to an area of high concentration
both need transport protein
Passive transport is a form of transport that does not require an input of energy. Examples include diffusion, osmosis and facilitated diffusion. On the other hand, active transport is a form of transport that requires an input of energy in the form of ATP (adenosine triphosphate). This energy is required for processes such as moving molecules against the concentration gradient.
what is difference between communication and transport
what is the difference between a diffusion and a dilution
The ATP hos to be provided because Active transport works against diffusion. its like the difference between a ball rolling down a hill (Passive Transport) and then having to push it up the hill (Active transport).
