Question

31. Refer to the figure at right. (7 pts) State the missing compound or process gut epithelia a. to capillaries) ucto b. GLUTS b. C. Na SGLT1 “c"-ase True or False- "a." is passively transported across the apical membrane into the enterocyte 32. (10 pts) Refer to the figure on the right, showing results from a glucose absorption experiment. The data were collected under two experimental conditions: Aerobic and Anaerobic, as shown. e 60 Aerobic gluoer tvo experimental conditions: E 50 40 30 20 10 How do these results support or refute our model of glucose uptake by active transport mechanisms? Anaerobic 0 10 20 30 40 50 Glucose (mML) The x-axis shows the concentration of glucose in solution administered into the intestinal lumen; the y-axis is the rate of glucose transported across the small intestine (mmoles per hour).

Explanation / Answer

a)Glucose( This is a symport of glucose along with Na+ ion due to the Na+ concentartion gradient)

b)Na+(3Na+ are pushed out for every K+ that comes in)

c)Na+/K+ ATPase(The above pump requires energy which is in the form of ATP. The enzyme is called Na+/K+ ATPase)

false. It is transported by the GLUT1 apical membrane transporter
