Technology, life, programming, travel and money. This is an A-level biology project. The whole project is reproduced here for your reference. They are used to speed up specific reactions in the cells. Catalase is an enzyme found in is yeast a substrate or enzyme such as potato and liver.

Hydrogen Peroxide from the cells. Add 2cm3 of yeast to one test tube. Hydrogen Peroxide, Yeast and water to ensure a fair test. I am timing how long it takes to produce 30cm3 of oxygen.

I carried out the above experiment and these results were obtained. All the times are in seconds. 97 Cm3 Oxygen produced per second, which is an increase of 1. The diagram below shows what happens. Hydrogen Peroxide the same for all the experiments. Hydrogen Peroxide, Yeast and Water each time. I used should be correct to the nearest mm3. This experiment could be improved in a number of ways.

Would be great to use this is a guideline. H, yes you can use this title. Good luck with your coursework. Am I allowed to use this for secondary data for my controlled assessment? Hi Zoë, yes you can use the data as long as you reference this web page. I was wondering how i could reference this page in APA format. The x axis is fine. Because he adds water to the yeast not to the peroxide to change the concentration.
