02/17/17 page 3Post-lab Quiz ResultsYou scored 100% by answering 4 out of 4 questions correctly.1. What happened when you increased the amount of ATP dispensed with the same concentration of sodium andpotassium on either side of the membrane?2. At what concentration of ATP were the sodium and potassium maximally transported?3. What was the effect of adding more Na+ -K+ pumps to the simulated cell?4. Describe the effect of adding glucose carriers to the sodium and potassium transport.
02/17/17 page 4Review Sheet Results1. Describe the significance of using 9 mMsodium chloride inside the cell and 6 mMpotassium chloride outside the cell,instead of other concentration ratios.2. Explain why there was no sodium transport even though ATP was present. How well did the results compare with yourprediction?3. Explain why the addition of glucose carriers had no effect on sodium or potassium transport. How well did the resultscompare with your prediction?4. Do you think glucose is being actively transported or transported by facilitated diffusion in this experiment? Explain youranswer.
