Pre-lab Quiz Results
You scored 100% by answering 4 out of 4 questions correctly.
1 The movement of sodium and potassium maintained by the Na+-K+ pump
You correctly answered: requires energy and is against a concentration gradient.
2 The sodium-potassium pump is classified as a(n)
You correctly answered: antiporter.
3 The sodium-potassium pump moves _____ sodium ions and _____ potassium ions simultaneously.
You correctly answered: 3, 2.
4 Solutes that require active transport for movement might be too large to pass or might be
You correctly answered: lipid insoluble.
Experiment Results
Predict Questions
1 Predict Question 1: What do you think will result from these experimental conditions?
Your answer: No Na+ will be transported.
2 Predict Question 2: Do you think the addition of glucose carriers will affect the transport of sodium
or potassium?
Your answer: No, it will not affect the transport of either ion.
Stop & Think Questions
1 Why did the sodium transport stop before the transport was completed?
You correctly answered: The ATP was depleted.
2 Why was the equilibrium for the solutes reached earlier?
You correctly answered: There were more pumps for transport.
