# How does temperature affect the rate of trypsin activity?

Extracts from this document...

Introduction

How does temperature affect the rate of trypsin activity? Aim Our aim is to see how temperature affects the rate of trypsin activity. Background In class we have done an experiment showing us, which PH levels are the best to use. Here is a graph to show the results. PH9 is shown to be the best. How does temperature affect the rate of trypsin activity? Background (continued) In class we have been studying enzymes. An enzyme speeds up a chemical reaction inside a cell. The enzyme itself isn't used up in the reaction, so this allows the enzyme to do the same thing again and again. ...read more.

Middle

Then put an equal amount of camera film in each test tube, then to use a stopwatch to time this, watch these test tubes and when the camera film goes clear you will know that the glatin has dissolved, stop the stopwatch and record the time it took. Repeat this three times. Fair test To make sure that this is a fair test I will use the same amount of camera film in each experiment. Safety To keep safe during this test wear safety glasses at all times, as I will be handling chemicals. Stand up so that if the experiment fell over I would be able to get away from the hot chemicals quickly. Results Temperature ( C) Time (S) ...read more.

Conclusion

I was also right as when the temperature started to get higher it started to take less time to dissolve, but after 40 C it started to take longer which I didn't think would happen so I was also wrong. Evaluation I think that my results and experiment went well, but for some of the times I did the experiment I forgot to heat up the enzymes before I put the camera film in, so if I were to do this experiment again then I would remember to heat up the enzymes before putting in the camera film. This would improve my results. Another way that I could improve this experiment is to do the experiment at more varied temperatures. 1 ...read more.
