Solved by ramonistry Exercise 1: Cell Transport Mechanisms and Permeability: Activity 5: Simulating Active Transport Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. The movement of sodium and potassium maintained by the Na+ -K+ pump You correctly answered: e. requires energy and is against a concentration gradient. The sodium-potassium pump is classified as a(n) You correctly answered: a. antiporter. The sodium-potassium pump moves _____ sodium ions and _____ potassium ions simultaneously. You correctly answered: b. 3, 2 Solutes that require active transport for movement might be too large to pass or might be You correctly answered: a. lipid insoluble. Experiment Results Predict 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?
