Table 1 shows that at 10°c, 20°c and 30°c the light absorbed by the solution is more than at 40°c, this is because the pepsin has not broken down as much of the egg albumen at lower temperatures as it has at 40°c so the spectrophotometer is picking up more undigested protein particles in these readouts. In this investigation, amylase is the enzyme, and starch is the substrate, ie the substance it acts upon in fact this work should add to your knowledge about the process of digestion which occurs in your body this practical work is designed to give you some experience about.
