Questions: McGraw-Hill Education Unlike simple diffusion, facilitated diffusion requires energy expenditure by the cell. True or False True False

The answer is False: facilitated diffusion does not require energy expenditure by the cell.

Explanation:

• Facilitated diffusion is a type of passive transport, which means it does not require energy from the cell. It relies on the concentration gradient to move substances across the cell membrane.
• In facilitated diffusion, specific transport proteins help move molecules across the membrane, but this process does not involve the use of cellular energy (ATP).
• Simple diffusion also does not require energy, as it involves the movement of molecules from an area of higher concentration to an area of lower concentration directly through the lipid bilayer.

In summary, both simple diffusion and facilitated diffusion are passive processes that do not require energy expenditure by the cell.
