Effect of pH (A) and temperature (B) on trypsin activity

WebEnzymes are sophisticated catalysts for biological processes. These practicals (and the practicals at intermediate level) give you opportunities to explore how enzyme activity changes in different conditions. Enzyme experiments often provide real ‘messy’ data, because their activity can change dramatically from one lesson to the next. WebThe optimum temperature is 37°, that is the average temperature inside the human body; the optimum pH level is 8.0. (Corporation, 2013) The purpose of this EEI and experiment is to calculate the rate in which the pH level of milk changes after it has been heated and the heated lipase is added.
