PhysioEx Lab Report Exercise 1 Activity 5 Exam Questions and Answers Already Passed
The movement of sodium and potassium maintained by the Na+ - K+ pump requires ____________ and
is ________ concentration gradient - Answers ATP, against
antiporter - Answers Sodium- potassium pump is classified as a(n)
Sodium-potassium pump moves _______ sodium ions and ____________ potassium ions simultaneously
- Answers 3, 2
Lipid insoluble - Answers Solutes that require active transport for movement might be too large to pass
or might be
What happened when the increased amount of ATP dispensed with the same number concentration of
sodium and potassium on either side of the membrane - Answers more ions were transported
At what concentration of ATP were the sodium and potassium maximally transported - Answers 2 mM
ATP
What was the effect of adding Na+- K+ pumps to the simulated cell - Answers Transport of the ions was
faster
Describe the effect of adding glucose carriers to the sodium and potassium transport - Answers There
was no change in the transport rate because glucose is transported independently
Why did the sodium transport stop before the transport was complete - Answers The ATP was depleted
Why was the equilibrium for the solutes reached earlier - Answers there was more pumps for transport
