no, but active transport on the other hand, does require transport proteins to transport the large molecules into the cell.

∙ 13y agoYes, it uses both channel and carrier proteins
Wiki User
∙ 11y agoNope, simple diffusion does not need transport proteins!
Wiki User
∙ 11y agono, because in passive transport, particles pass straight through the cell membrane without the cell using atp

Does passive transport rely on diffusion or energy?
No it does not..........simple diffusion is nauture
Compare and contrast diffusion and facilitated diffusion?
They both require a trans membrane protein. Facilitated diffusion does not require energy whereas active transport requires energy. Facilitated diffusion takes place when there is a net movement of molecules from a region of high concentration to a region of low concentration whereas active transport takes place when there is a net movement of molecules from a region of low concentration to a region of high concentration.
Which of these nephron transport processes does not show saturation at high solute values a. coupled cotransport b. facilitated diffusion c. active transport d. simple diffusion?
d. simple diffusion
How are facilitated diffusion and active transport similar ad how do the differ?
both these processes do the transport against the concentration gradient uh no facilitated diffusion doesnt go against the gradient, the similiarity is that they both use carrier protiens
Why is facilitated diffusion faster than simple diffusion?
Facillatated diffusion is faster than simple diffusion when solute concentration is low because it uses channels to transport molecules throught the lipid bilayer. Simple diffusion depends upon concentration gradients so the net movement of diffusing molecules depends on the concentration gradient, thus the rate of diffusion is directly proportional to the concentration gradient. Simple diffusion is also a type of passive transport, which requires no energy input, whereas facilitated diffusion is protein mediated transport. Passive diffusion of solute into a cell is linearly related to the concentration of solute outside the cell. Carrier proteins increase the rate of diffusion by allowing more solute to enter the cell. Facilitated diffusion, however, approaches a maximum rate as the carrier proteins become saturated with solute.
What are the three transport processes that do not require cell energy?
Passive Transport,Facilitated Diffusion, and Simple Diffusion
How is active transport different than simple and facilitated diffusion?
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
How is faciliated transport similar to simple diffusion?
Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.
Does simple diffusion require ATP?
No only active transport requires ATP.
Does passive transport rely on diffusion or energy?
No it does not..........simple diffusion is nauture
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
What are the three types of transport proteins?
Carrier Proteins and Channel ProteinsReceptor ProteinsGlycoproteinsSource: Currently doing AS-Level Biology.
In facilitated diffusion which process does not require energy?
Simple and facilitated diffusion are a part of passive transport. This refers to the movement of molecules, atoms and ions across the cell membrane. In both of these processes, molecules move from areas of high concentration to areas of lower concentration because equilibrium is trying to be maintained in living organisms. Simple diffusion just happens randomly and without any aides. Facilitated diffusion uses proteins in the cell membrane to guide polar molecules and ions in and out of the membrane (always to areas of lower concentration) and DOES NOT require ENERGY.Only active diffusion requires energy.
How does diffusion take place in the body?
P.I.S.O.- Potassium in Sodium out facilitated diffusion, active transport , and passive transport and simple diffusion.

d. simple diffusion
What structures allow small particles to cross the cell membrane?
Small particles can cross the cell membrane through simple diffusion, facilitated diffusion, or active transport. In simple diffusion, particles move from an area of high concentration to low concentration without the need for energy. Facilitated diffusion involves the use of protein channels or carriers to aid in the movement of particles. Active transport requires energy and transport proteins to move particles against their concentration gradient.
