the correct answer is b....coz facilitated diffusion is well facilitated...with the help of carrier molecules....no direct invlvemnt of ATP (energy ) is required for it to take place...the rest are forms of "active" transport that require energy expenditure in the form of ATP... :)

The correct answer to this one is B. Facilitated diffusion requires a carrier molecule but the process is passive and requires no ATP. All others listed are active processes and takes ATP to accomplish. Answer B and move on.

the perfect answer to this one is B. Facilitated diffusion demands a provider molecule regardless of the indisputable fact that the mind-set is passive and demands no ATP. All others listed are lively thoughts and takes ATP to end. answer B and bypass on.
