Human trypsin has an optimal operating temperature of about 37 °C. In contrast, the Atlantic cod has several types of trypsins for the poikilotherm fish to survive at different body temperatures. Cod trypsins include trypsin I with an activity range of 4 to 65 °C (40 to 150 °F) and maximal activity at 55 °C (130 °F), as well as trypsin Y with a range of 2 to 30 °C (36 to 86 °F) and a maximal activity at 21 °C (70 °F). WebThe optimum temperature and pH for the trypsin are 65 C and pH 9.0, respectively. How does temperature affect the rate of reaction of trypsin? The higher the temperature will be, the quicker the solution will become clear, and so the rate of reaction will increase. flyfly repuestos https://omnimarkglobal.com
