The effect of copper sulphate on catalase enzymes

Extracts from this document...

Introduction

The effect of copper sulphate on catalase enzymes Aim My aim is to find out the effect of copper sulphate on catalase enzymes Prediction I predict is that I think the less copper sulphate in dilute water will speed up the reaction so more oxygen is produced. The way I know this is copper-sulphate metals inhibit, which means slows down the reaction. The two ways in which it inhibits the enzymes are Metals binds to the enzymes and distort the shape of the enzymes which active the site, therefore this slows the reaction. ...read more.

Middle

I will repeat till I have five test tubes and in the last test tube I have 0.025moles of copper sulphate left the extra 5cm I will throw it away. Secondly I will take out 2cm from each test tube and add liver into the solution and put a bung on top. In washing up bowl I have put inside water. Inside the washing up blow there is measure cylinder upside down full of water with a pipe going from the measure cylinder to the test tube. ...read more.

Conclusion

half wrong as you can see from the results table, because in 2 moles of CuSO4 solution 11cm of oxygen was produce so some where in the experiment it went wrong because should have been 5cm. But is I had repeated the experiment than that would have given me average set of results. Evaluation The way I could have made my experiment better was to have repeated the test/experiment so it would have given be an average set of results. Than every thing that I had said in my prediction would have been correct. Asma Habib 12SG ...read more.

    E.g., 10ml of solution 1 in 24 pots (batch 1), 10ml of solution 2 in 24 pots (batch 2) etc. I will do this using a micropipette. So that each experiment is run separately and the solutions affect each batch of seeds separately for statistically viable results.
