Which of the following statements regarding membrane transport proteins is NOT true? Facilitated transport is required to move any molecule against its concentration gradient. Both transporter proteins and ATP-powered pumps represent active transport. Uniporter transport is fast, reversible, and highly specific. Uniporters move ions faster through membranes than do ion channels.

Uniporters me be ions faster through membranes than do ion channels

Explanation:

Membrane transport protein is a membrane protein that help to function in moving ions, small molecules and macromolecules across a biological membrane.The proteins may assist in the movement of substances by facilitated diffusion or active transport.

Uniporters are membrane transport protein that move one species of substrate across the cell membrane.ion channels move ions faster than uniporters membrane because they are pore forming membrane that allow ions to pass it's pore freely.

substitution is the answer in this case
