Josh Laster Biology 111 – 523 Diffusion Across a Plasma Membrane The “Diffusion Across a Plasma Membrane” experiment was designed to illustrate how the digestive system works. The small beaker used represented the head and crop of a caterpillar. Four pipettes of cooked starch were placed in the small beaker to depict the caterpillar eating a leaf containing starch. A-amylase is a digestive enzyme in the mouth that breaks down starch into glucose. Four full pipettes of the A-amylase were added to the small beaker and mixed with the starch solution. This mixture gets stored in the crop (the small beaker) before it goes into the intestine. Two dialysis bags were used (each representing an empty gut). One dialysis bag was filled with just cooked starch to be used as the control and the other dialysis bag was filled with the solution that was in the small beaker (A-amylase and cooked starch). Both bags were placed in two separate large beakers. Each beaker was filled three-fourths of the way full with water.
