The paper will include a method telling you what to do which you have to follow exactly. Then there are questions hat you have to answer based on what you know from the spec. are given a load of equipment and an exam-style paper. Does the teacher literally walk around the class whilst we're are doing the experiment, occasionally looking at what individuals are doing?

You follow the method and then at some point it will tell you to record the results which will be qualitative(colours etc.). The paper will include a method telling you what to do which you have to follow exactly. Then there are questions hat you have to answer based on what you know from the spec. Also I dont know if this makes sense but Ive heard we can retake if we dont do well.

The quantitative is probably measuring the rate of a reaction with an enzyme varying p H or temperature. Make sure that you know everything in the textbook on proteins by heart. Edit: Surely you can't handle benzene, conc acids, bromine etc. Hey, I was wondering if you did the same experiment- My qualitative one is about plasma proteins and we're investigating how (I think fast I dont know) they make a precipitate in different substances like HCL and ethanol.

The quantitative is probably measuring the rate of a reaction with an enzyme varying p H or temperature. I know one of the questions is "why is the HCL not put under the highest conc" and "why is using ethanol and advantage."- What do you think?

On Tuesday I have my Qualitative practical for OCR AS level biology.

Im SO worried because our teacher literally went over all the experiments we would do in onelesson and said all the practicals would be over within a just a week- she says they're easy but I dont think they will be easy :/ I did IGCSE last year which involved no practicals it was just exam based, so I have no experience of it.Oh and my quantitative one is a beetroot experiment, which ive done before but am quite vague on.Hey, I was wondering if you did the same experiment- My qualitative one is about plasma proteins and we're investigating how (I think fast I dont know) they make a precipitate in different substances like HCL and ethanol.Could you please please please help and give me any tips as to what to revise and expect for these practicals qual, quan, and evaluative. Enzymes such as Catalase are protein molecules which are found in living cells.There's only one mark for the actual carrying out of the experiment, so I would not worry too much on the actual experiment process but the theory that surrounds the experiment which make up the majority of the marks. Does the teacher literally walk around the class whilst we're are doing the experiment, occasionally looking at what individuals are doing?Also I dont know if this makes sense but Ive heard we can retake if we dont do well.They are used to speed up specific reactions in the cells.They are all very specific as each enzyme just performs one particular reaction.The majority of the marks come from the questions, which they mark afterwards.1 mark comes from lab safety, which you automatically lose if you forget your lab coat for example.

    The rate of an enzyme- catalyzed reaction increases with temperature up to a maximum, called the optimum temperature. Most enzymes work best optimum temperature between 30c-40c.
