Question

As shown in Figure 6.15 in the textbook, the uptake of glucose into cells uses energy gained from primary active transport by the sodium-potassium pump. Which statement best describes the use of this energy? O The diffusion of K+ into the cell establishes a concentration gradient for glucose to follow. O Antiporters move Na+ out of the cell and glucose molecules in O Hydrolysis of ATP directly moves glucose against its concentration gradient. O The concentration gradient of Na+ drives the coupled transport of Naand glucose. O The phosphorylation of the sodium-potassium pump allows glucose to diffuse into the cell.

Explanation / Answer

Which statement best describes the use of this energy?

D) The concentration gradient of Na+ drives the coupled transport of Na+ and glucose.
