Diffusion (passive transport) needs no energy to take place, and therefore no need for transport or carrier protiens.
Active transport uses carrier protiens, as the cell needs to work against a concentration gradient. This requires energy.
Diffusion can take place outside of cells
Active transport can't take place outside of cells.
What else can I help you with?
Does simple diffusion require transport proteins?
No, simple diffusion does not require transport proteins. It is a passive process where molecules move from an area of higher concentration to an area of lower concentration directly through the lipid bilayer of the cell membrane. Transport proteins are involved in facilitated diffusion and active transport.
What is the difference between active and passive cellular transport?
Active transport requires energy; passive transport does not.
How is active transport different from passive transport, and what are two ways in which they contrast in terms of their mechanisms?
Active transport and passive transport are two methods by which substances move across cell membranes. Active transport requires energy input from the cell, usually in the form of ATP, to move molecules against their concentration gradient. In contrast, passive transport does not require energy and relies on the natural movement of molecules from areas of high concentration to low concentration. One way in which active and passive transport contrast in terms of their mechanisms is that active transport uses specific carrier proteins to transport molecules, while passive transport can occur through simple diffusion or facilitated diffusion. Another difference is that active transport can move molecules in both directions across the membrane, while passive transport typically only moves molecules in one direction.
What are two forms of passive transport of a cell?
Two forms of passive transport (or transport not involving energy/ATP) are diffusion and facilitated diffusion. Another form is osmosis. Also keep in mind that passive transport is for smaller particles.
How is active transport different from possive transport?
Active transport need energy from outside to perform a function whereas in passive transport the function is performed on the principle of physics. for example active absorption of minerals by the plant roots require energy from respiration whereas passive absorption is achieved by law of diffusion.
What are the four types of proteins found in the cell membrane?
Actually, bilipid "heads" form the layers of the membrane, but there are carrier proteins that transport objects into and out of the cells. These carrier proteins use either active or passive transport to get objects across the membrane. Active transport uses energy, while passive transport doesn't need to use energy to get items across. Hope this helps!!!
Does simple diffusion require transport proteins?

Transport proteins are involved in facilitated diffusion and active transport.
Does facilitated diffusion require ATP?
In cells, passive diffusion is energy independent and therefore does not require ATP. This is opposed to active transport which requires either energy in the form of ATP or a charge gradient to move a molecule or ion across the membrane.
Passive transport that moves particles away from areas is called what?
Passive transport that moves particles away from areas is called facilitated diffusion. This process uses transport proteins to help molecules or ions pass through the cell membrane, moving from areas of higher concentration to areas of lower concentration without using energy.
What is the difference between active and passive cellular transport?
Active transport requires energy; passive transport does not.
Is pinocytosis acitve or passive transport?
It is the active transport of liquids in vesicles into and out of a cell so it uses metabolic energy, thus active

Does facilitated diffusion require the Cell to use energy?
No, there is no ATP used in facilitated diffusion, because it is a form of passive transport. It only differs from normal diffusion in that it uses transport proteins to move larger or more polar molecules across the membrane of the cell.
When are active and passive transport and their types used?
Active transport uses energy in the form of ATP. Active can force electrons against the electron gradient as in the electron transport chain. Passive transport does not use energy and an example of passive transpost is osmosis.
