3. Why was there not 100% recovery of the Na+ Cl- solute with any of the membranes?4. An increase in blood pressure would probably initially __________ filtration in the kidneys.You correctly answered: b. increase the rate of
02/17/17 page 4Review Sheet Results1. Explain in your own words why increasing the pore size increased the filtration rate. Use an analogy to support yourstatement. How well did the results compare with your prediction?2. Which solute did not appear in the filtrate using any of the membranes? Explain why.Your answer:3. Why did increasing the pressure increase the filtration rate but not the concentration of solutes? How well did the resultscompare with your prediction?
1. The movement of sodium and potassium maintained by the Na+ -K+ pumpYou correctly answered: e. requires energy and is against a concentration gradient.2. The sodium-potassium pump is classified as a(n)You correctly answered: a. antiporter.3. The sodium-potassium pump moves _____ sodium ions and _____ potassium ions simultaneously.You correctly answered: b. 3, 24. Solutes that require active transport for movement might be too large to pass or might beYou correctly answered: a. lipid insoluble.02/17/17 page 1
02/17/17 page 2Experiment ResultsPredict Question:Predict Question 1: What do you think will result from these experimental conditions?Your answer : c. No Na+ will be transported. Predict Question 2: Do you think the addition of glucose carriers will affect the transport of sodium or potassium?Your answer : d. No, it will not affect the transport of either ion. Stop & Think Questions:Why did the sodium transport stop before the transport was completed?You correctly answered: c. The ATP was depleted.Why was the equilibrium for the solutes reached earlier?You correctly answered: c. There were more pumps for transport.Experiment Data:Run NumberSoluteATPStart Conc.
