Absorption of Nutrients Lab

The Starch Digestion Lab simulated the digestion of starches into sugars by the enzyme amylase in the saliva in the animal’s mouth. The dialysis tubing simulates the semi-permeable membrane of the cell allowing the smaller sugar molecules to pass through while larger starch molecules cannot pass through the membrane. Iodine in the presence of sugar turns amber yellow color while Benedicts solution in the presence of sugar turns any color besides the original blue color.
