Answer:
c. facilitated diffusion requires an integral protein
Explanation:
Facilitated diffusion is process of the spontaneous passive transport (high to low concentration) of molecules or the ions across biological membrane by using specific trans-membrane proteins.
Facilitated transport does not require chemical energy from the ATP hydrolysis as it is a passive transport.
On the other hand, simple diffusion is the transport of the molecule from high tot low concentration without the use of a specific molecule.
