1
In the small intestine of a healthy person, glucose passes:
A)from the inside or lumen, through the gut wall, and into the blood.
B)from the blood, through the gut wall, and into the inside or lumen.
C)equally in both directions across the wall of the small intestine.
2
In this lab, the small intestine was everted, or turned inside-out. Therefore, in this orientation, glucose would pass:
A)from the lumen of the small intestine, across the gut wall into the incubation medium.
B)from the incubation medium, across the gut wall into the lumen of the small intestine.
C)across the wall in both directions.
3
Look at your data for the tubes labeled 'gtr' and 'r'. The value for 'gtr' (the solution inside the everted gut segment) was:
A)smaller than the value obtained for the incubating solution ('r').
B)about the same as the value obtained for the incubating solution ('r').
C)larger than the value obtained for the incubating solution ('r').
4
If the final data values indicate the amount of glucose present in each solution, your data for tubes 'gtr' and 'r' indicate that:
A)there was less glucose inside the everted gut segment than in the incubating solution.
B)there was the same amount of glucose inside the everted gut segment as in the incubating solution.
C)there was more glucose inside the everted gut segment than in the incubating solution.
5
Look at your data for the tubes labeled 'gto' and 'r+o', where Ouabain was present inside the gut segment. The value for 'gto' (the solution inside the everted gut segment) was:
A)smaller than the value obtained for the incubating solution ('r+o').
B)about the same as the value obtained for the incubating solution ('r+o').
C)larger than the value obtained for the incubating solution ('r+o').
6
If the final data values indicate the amount of glucose present in each solution, your data for tubes 'gto' and 'r+o' indicate that:
A)there was more glucose inside the everted gut segment than in the incubating solution.
B)there was the same amount of glucose inside the everted gut segment as in the incubating solution.
C)there was less glucose inside the everted gut segment than in the incubating solution.
7
Ouabain is known to:
A)abolish the activity of sodium/potassium-ATPase pumps.
B)close sodium channels.
C)inhibit the co-transportation of glucose and sodium.
D)hyperpolarize the cell membrane.
8
Where are the sodium/potassium-ATPase pumps in the absorptive cells that line the small intestine?
A)In the apical membrane, next to the lumen of the small intestine.
B)In the basolateral membrane, next to the interstitial fluid and capillaries.
C)Distributed evenly around the absorptive cells.
9
In this lab, the small intestine was turned inside-out and the Ouabain was placed inside the everted gut. Therefore, in this orientation, Ouabain was in direct contact with:
A)the apical membrane of the absorptive cells, next to the lumen of the small intestine.
B)the basolateral membrane of the absorptive cells, next to the interstitial fluid and capillaries.
C)Distributed evenly around the absorptive cells.
10
In this lab, Ouabain was in direct contact with the pumps in the basolateral membrane of the absorptive cells. Would you get the same results if you placed Ouabain in the incubating solution?
A)No, because Ouabain in the solution would not be in direct contact with the sodium/potassium-ATPase pumps.
B)Yes, because Ouabain in the solution would not be in direct contact with the sodium/potassium-ATPase pumps.
C)No, because Ouabain in the solution would be in direct contact with the sodium/glucose transporters.
D)Yes, because Ouabain in the solution would be in direct contact with the sodium/glucose transporters.
