Trypsin (enzyme classification number 3.4.21.4) was first described in the late 1800s as a proteolytic activity present in pancreatic secretions. The reaction converted hydrogen peroxide to water and oxygen and oxygen production was used as a measure of enzyme activity. Temperature. As an enzyme works it combines with its substrate and converts it to product(s). Though the temperature is a major factor affecting the rate of reaction, there are other factors that play an important role. Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.
