Question

unlike simple diffusion, facilitated diffusion requires energy expenditure by the cell. true or false

Explanation:

To determine the answer, we analyze the concepts of simple diffusion and facilitated diffusion. Simple diffusion is the passive movement of molecules down their concentration gradient, requiring no energy. Facilitated diffusion also involves the movement of molecules down their concentration gradient but with the help of transport proteins. Importantly, neither simple diffusion nor facilitated diffusion requires the cell to expend energy (energy - requiring transport is active transport). So the statement "Unlike simple diffusion, facilitated diffusion requires energy expenditure by the cell" is false.

Answer:

False
