Hey,
Is your write up going to be a prac report or questions based on the prac result? If it’s the latter you can read about what types of questions you might see
here.
If it’s a prac report it could either be entirely up to you or answering structured questions (your teacher should have told you which). If it’s entirely up to you, you just need to follow the normal introduction/method/results/discussion/conclusion format.
If it’s questions it will likely be things like
-what is your IV/DV
-what is your aim
-what generalisations can be made from your results
-are your results reliable/valid/accurate? Why/why not?
Basically just the same stuff you would include in a prac report but more structured.
Hydrogen peroxide (H2O2) is broken down into water and oxygen by an enzyme called catalase. I would say that you should know the formula (2H2O2—>2H2O + O2), It has to start with 2 hydrogen peroxide or you only get half an oxygen molecule. You should also be aware of limiting factors (substrate & enzyme concentration, temperature, etc) and what a graph showing that information would look like.
