You don't need to memorise for all different reactions (unless that reaction is elsewhere in the spec), as the same experimental set up can essentially be used for most, e.g. you need a substrate, an enzyme and a way to study the enzyme action. You also need to think about which variable you will change and how to keep all the others the same. Reviewing the others for familiarity is not a bad idea, so if you are asked in an exam it is not a surprise, but they won't be testing the minutiae of the experimental set-up - they are testing your understanding of practical science and that you know how to apply scientific rigour, i.e. how to collect meaningful results, identify sources of error, present/analyse your results and come to logical conclusions (also maybe ways that the experiment could be improved; this would likely be a 1 mark "suggest" question).
Hope that makes sense. Good luck!
