Emma Lazarus 10Y1 Pepsin and Protein Question Is the rate at which Pepsin digests protein affected by temperature? Prediction I predict that it is affected by temperature. The optimum temperature will be between 30°C and 40°C. This is because the average human body temperature is 37°C. At 0-20°C (which includes the groups 0-10 and 10-20) the pepsin will not digest the protein for a long time. This is because it is a too cold environment for the enzyme to work most effectively and quickly. At 20-30°C the pepsin will work slightly more quickly than at 0-20, but not as well as at 30-40, because it is reaching the optimum temperature, though it is not quite there yet. At the higher temperatures (i.e. 40-70°C) the enzymes will not work as well. You may think that, using the pattern up to 30-40°C, the higher the temperature, the quicker pepsin works. But this is not the...
