ENZYMES

Extracts from this document...

Introduction

InVESTIGATING ENZYMES Aim To find out how enzymes are affected by temperature. Method . Mix starch and amylase together to get a solution . Place it in 6 Beakers . Place this mixture in 6 Electric baths at different temperatures. E.g. 20,25,30,35,40,and 45 . Use a pipette to put 2 drops of the solution at 20oC in a spotting tile . Then add two drops of Iodine (to test if starch is present-the solution will go black) . Start a stopwatch and start adding the drops . Repeat for all the temperatures. Repeat the entire experiment. . Find the average . Record the results Equipment . Six beakers . Pipette . ...read more.

I will be able to test it by recording its results at different temperatures. The experiment will work best at 35oC as its closest to body temp. ANALYSING The results show me that: Enzymes are affected by temperature, which by adding the solution drops, the colour changed from black to a lighter colour. It occurred at different speed and heat temperatures. The results show the experiment worked as its best 35oC.This shows that enzymes are affected by temperature. So my Prediction was: "That I will be able to see how enzymes can be affected by temperature, as when I start adding the drops, the colour will change from black to a lighter colour. ...read more.

Conclusion

So the higher the temperature the faster starch breaks down. However, the experiment works always best at 35oC as its closest to body temperature. RESULTS A table to show the results of when and how Enzymes are affected by temperature. EVALUATION I think the experiment worked well because: The experiment and results showed up how I expected them to because the higher the temperature, the lower the time and 35 C would be the best temperature for breaking food down. I know the results are accurate because: This was a fair test. I used a higher temperature each time and made sure my timing was and measurement was accurate. I could improve the experiment by: Making it more of a fair test, by making sure that the time is proper accurate and there's equal amounts of both solutions, and lastly that the timing is more accurate. ...read more.
