7 A student investigаtes the mоvement оf substаnces frоm the gut into the blood using а model. The Visking tubing bag represents the gut and water represents the blood. (see addendum Question 7, Figure 7.1). Visking tubing is permeable to small molecules. 7.1 The student puts different solutions of various substances into the bag. After 20 minutes he carries out food tests on the water 7.1.1 Complete the table to show the results obtained by the student. One has been done for you. Use the numbers in the table to write down your answers. Solution in bag Starch present in water Glucose present in water starch only no no starch and glucose [a] [b] starch and maltase [c] [d] starch and boiled amylase [e] [f] (3) 7.1.2 Explain how the volume of the bag would change when it only contains starch solution. (2) 7.1.3 Describe the test the student should use to find out if glucose is present in the water. (3) 7.2 Explain how you could use this apparatus to investigate the effect of bile on the digestion of lipids. (4)
