Question

one transport mechanism to move sugars into cells against their concentration gradient is
multiple choice
facilitated diffusion
symport with sodium
simple diffusion
antiport with sodium
osmosis

Explanation:

Facilitated diffusion and simple diffusion move substances down their concentration gradients. Antiport with sodium moves substances in opposite directions relative to sodium. Symport with sodium is a secondary - active transport mechanism that can move sugars into cells against their concentration gradient by coupling with the movement of sodium ions down their concentration gradient.

Answer:

B. symport with sodium
