Pre-lab Quiz Results
You scored 50% by answering 2 out of 4 questions correctly.
1 Molecules need a carrier protein to help them move across a membrane because
Your answer: they are not lipid soluble.
Correct answer: they are lipid insoluble or they are too large.
2 Which of the following is true of facilitated diffusion?
You correctly answered: Movement is passive and down a concentration gradient.
3 Examples of solutes that might require facilitated diffusion include
You correctly answered: all of the above.
4 Which of the following would not affect the rate of facilitated diffusion?
Your answer: steepness of the gradient.
Correct answer: the amount of intracellular ATP.

Predict Questions
1 Predict Question 1: What effect do you think increasing the number of protein carriers will have on
the glucose transport rate?
Your answer: The glucose transport rate will increase.
2 Predict Question 2: What effect do you think adding Na+Cl- will have on the glucose transport rate?
Your answer: There will be no change in the glucose transport rate.
Stop & Think Questions
1 What happened to the glucose transport rate when the glucose concentration was increased from 2
mM to 8 mM?
You did not answer this question.
Correct answer: The glucose transport rate increased.
