Textbook Question
Chapter 8, Problem 8.12PS
Ouabain Inhibition. Ouabain is a specific inhibitor of the active transport of sodium ions out of the cell and is therefore a valuable tool in studies of membrane transport mechanisms. Which of the following processes in your own body would you expect to be sensitive to inhibition by ouabain? Explain your answer in each case.
(a) Facilitated diffusion of glucose into a muscle cell
(b) Active transport of dietary phenylalanine across the intestinal mucosa
(c) Uptake of potassium ions by red blood cells
(d) Active uptake of lactose by the bacteria in your intestine
