High temperature and enzyme activity
WebThe water bath in the experiment was at 24ºC – room temperature. It took 5 minutes for the temperature of the solution to heat up; however the results seem variable as it cooled to 24ºC at 10 minutes, then went back up to 25ºC at 15 minutes. The water bath in this experiment was at 15 ºC. WebFactors that affect enzyme activity Temperature: Generally, a higher temperature speeds up a reaction while a lower temperature slows it down. ...
