Best Answer

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

active transport requires the usage of energy in the form of ATP to move something against is concentration gradient. Facilitated diffusion is a form of simple diffusion in that the substance moves along with its concentration gradient, but it requires the use of a transport protein. Polar molecules are unable to passively diffuse through the lipid bilayer because of its hydrophobicity, even if it is moving with its concentration gradient. Membrane transport proteins are required to allow them to be moved in or out of the cell, but they do not require ATP to complete the process. Similar to active transport, they require the use of a membrane protein for movement through the membrane, but unlike active transport, it does not require the use of any energy.

Is diffusion through ion channels a form of active transport?

Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.

What does active transport and facilitated diffusion have in common?

Active transport is when proteins move substances into the cell while expending energy. Facilitated diffusion is the movement of chemicals through a protein into a cell.
