One transport protein we'll come back to multiple times in the course is the sodium-potassium pump. What happens as a result of the action of the sodium-potassium pump? Choose both correct answers. Sodium and potassium ions move across the membrane passively down their gradient. There is potential energy in an ion gradient across the membrane that can be used to drive other processes. Sodium and potassium ions are at highest concentration outside the membrane. An electrochemical gradient is established across the membrane. ATP is synthesized from ADP and inoragnic phosphate.

Step 1
Sodium and potassium ions move across the membrane passively down their gradient: This statement is incorrect. The sodium-potassium pump moves ions against their concentration gradient, which requires energy. Show more…
