the energy required to move molecules results from a high-energy bond.

molecules are moved by the use of vesicles.

a preference of a carrier protein for a substance is demonstrated based on the differing affinities of the carrier for the substrates.

a carrier molecule has the ability to transport only one molecule or a group of closely related molecules.

 a group of carrier proteins is operating at its maximum rate.

active transport

exocytosis

All of the answers are correct.

osmosis

passive transport

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

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

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

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

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