... Cylinder Controlled. Amount of Gelatine. cm. Ruler Prediction: I am going to change the temperature that the trypsin works at. The time taken for the trypsin to digest the gelatine will change because of this. I predict that the temperature that the trypsin works at best (and so the time that the gelatine is digested quicker at) will be about 37?C, because this is body temperature. Hypothesis: Trypsin is one of the three principle digestive enzymes which are called Proteases. the other two are Pepsin and Peptidases. During the digestion process, Trypsin acts with the other Protease enzymes to break down protein molecules to their component Peptides and amino acids. Trypsin is produced in the pancreas but works in the small intestine. Gelatine is a protein, and will be digested by the Trypsin. I predicted that the trypsin will work best at 37?C. This is because enzymes break down the substrate by a method known as the "lock ...
