Question

Facilitated diffusion and active transport differ in that:

a) facilitated diffusion uses cell membrane proteins to move substances, whereas active transport does not.

b) facilitated diffusion moves water across the cell membrane, whereas active transport does not.

c) ATP is necessary for active transport, but not for facilitated diffusion.

d) facilitated diffusion uses a substrate to bind to a protein carrier, whereas active transport does not.

e) potential energy is required for active transport but not for facilitated diffusion.

Active carry an d utilizes energy and goes opposite to the concentration grade.

Facilitated diffusion does not need energy and utilizes ion channels or transport proteins to proceed things down the concentration grade.

Active transport and utilizes energy and goes opposite the concentration grade.
