Diffusion with a channel protein?
They are the channels by which molecules enter in facilitated diffusion.
How do you transport proteins in a cell make it easier for certain molecules to diffuse across a membrane?
If there's a transfer protein then its NOT diffusion ... its active transport.
What type of transport is it when gluclose molecules move into a cell?
passive. any transport that is diffusion to get into a cell is passive.
Is carrier proteins passive transport or active transport?
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.
What is the difference between diffusion and active transport?
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
Diffusion with a channel protein?
They are the channels by which molecules enter in facilitated diffusion.
What process involves the use of specific carrier molecules?
two processes requiring the use of protein carrier molecules?

Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
Why does active transport require more energy than osmosis or facilitated diffusion?
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
This is the process whereby a protein assists in simple diffusion?
Active transport
In what ways do molecules move?
it moves by diffusion, osmosis and active transport
How is diffusion different from active transport?
active transport is different from diffusion. active transport has to do with the movement of chemical substance through a gradient of concentration. diffusion has to do with requiring the expenditure of energy
What is the difference between facilitated diffusion with the help of a carrier molecule with the help of a transport protein?
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.
