Does anyone have any pracs on the pH rate of reaction on enzymes (catalase) - for year 12 Biology ??
Thanks in advance

Re: pH rate of reaction
Hi Marg,
We did this a couple of weeks ago using 6% H2O2 and pulped kiwi fruit (I never use liver!).
I made up solutions of known pH using the attached "recipe" and it worked a treat.
Cheers

Re: pH rate of reaction
This is my interpretation of an enzyme prac I found here many years ago.
From what i understand of the sylabus it doesn't have to be at X pH just show that pH makes a difference with different enzymes.
We found that the dilute NaOH and HCl worked well with no mucking around trying to get the pH at an exact number. It uses spinach or capsicum and cleans up easily.
