No, diffusion is passive transport.

Active transport would be when there are actual proteins and structures involved in the transportation of molecules/chemicals/etc..

A sure sign is that all of these (that I know of) require ATP.

An example would be the Sodium-Potassium Pump located along one's neurons which actively pumps (aka. transports) sodium and potassium back and forth across the membrane to build up potential charge. This is how "signals" are sent down neurons and around the body.

Is diffusion active transport?

No, it is passive transport because it does not require any of the cell's energy.


What type of transport is it when gluclose molecules move into a cell?

Glucose molecules entering a cell typically occurs through facilitated diffusion, which is a type of passive transport. This process involves the movement of glucose across the cell membrane with the help of specific transporter proteins.


Why is diffuse an example of passive transport?

Diffusion is an example of passive transport because an organism need not expend energy to accomplish diffusion. In diffusion, molecules simply cross a membrane from an area of higher concentration to an area of lower concentration.


The different between passive transport and active transport?

Active transport requires energy; passive transport does not.


Does passive transport rely on diffusion or energy?

No it does not..........simple diffusion is nauture


Is water an active or passive transport?

Water can use both passive and active transport mechanisms. Passive transport involves movement of water molecules across a membrane without the need for energy, while active transport involves the use of energy to move water molecules against their concentration gradient.


What is the defference between active transpors and passive transport?

Active transport requires energy input to move molecules against their concentration gradient, while passive transport moves molecules along their concentration gradient without energy input. Active transport is typically carried out by transport proteins, such as pumps, while passive transport can occur through simple diffusion or facilitated diffusion.


What type of Transport in a cell does not require energy?

Passive transport does not require energy as it relies on the natural movement of molecules from an area of high concentration to an area of low concentration. Examples include diffusion, osmosis, and facilitated diffusion.


What kind of molecules can move across the membrane For simple diffusion?

Passive transport is dependent on the permeability of the cell membrane, which, in turn, is dependent on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis.Simple diffusion is the unassisted passage of small, hydrophobic, nonpolar molecules.
