A form of passive transport that uses transport proteins-?
Carlcarlos10
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.

Does simple diffusion require transport proteins?
no, but active transport on the other hand, does require transport proteins to transport the large molecules into the cell.
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.
Does facilitated diffusion use transport proteins?
Passive diffusion across lipid bilayers :Small apolar molecules like O2 and C02, or ethanol diffuse across the bilayer.Polar or charged molecules do not cross the membraneActive transport :Membrane proteins, such as pores, canals, transporters, facilitators regulate diffusion across membranes.Within membranes :Lipid and proteins diffuse laterally (on the membrane plane).
How do molecules move by passive transport?
During passive transport. The particles do this with out energy. During osmosis is also passive tranport. Active transport uses energy or ATP.
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 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.
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.
Does simple diffusion require transport proteins?
no, but active transport on the other hand, does require transport proteins to transport the large molecules into the cell.
Does passive transport uses the cell wall?
Passive transport occurs inly with plasma membrane.
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
What are two forms of passive transport of a cell?

The different between passive transport and active transport?
Active transport requires energy; passive transport does not.
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.
If the substance entering the cell was in higher concentration inside the cell then outside the cell what type of transport would be required?
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
Which type of transport uses energy passive or active transport?
Active transport because it move up the concentration gradient which requires energy to do so. Where as the passive transport goes down the concentration which does not need energy.
Does facilitated diffusion use transport proteins?
Passive diffusion across lipid bilayers :Small apolar molecules like O2 and C02, or ethanol diffuse across the bilayer.Polar or charged molecules do not cross the membraneActive transport :Membrane proteins, such as pores, canals, transporters, facilitators regulate diffusion across membranes.Within membranes :Lipid and proteins diffuse laterally (on the membrane plane).
