I wrote, one of the products had a NH3 group. Then I wrote that all had methyl groups in different places, so each had a different structure.

There was a NH3 group?

They had different groups attached to different nitrogen atoms. For example there were two of them with CH3 groups attached to a particular nitrogen whereas the other was attached to a hydrogen.

i said so thnx anyway

Yeah, I'm pretty sure. It was in the middle product.

holy crap! you found it!!! I put there were different amount of hydrogen present and different amounts of CH3 present.

why there are several enzymes for breaking the coffeine

[viclupa1]

what did people put for the reason why there are many different enzymes present in the breakdown of caffine?

Hmm, it even talks about that enzyme on the page

I put that firstly each enzyme catalyses a specific reaction and will lead to one product forming. There are three different products formed in the breakdown therefore three different enzymes have to be involved.

so what were the answers of the tryglyceride one?

Well it breaks down to glycerol and fatty acids and they are joined by ester bonds

Dammit, I think I only got 1 mark out of 3... I said something similar to what you said about the enzyme catalysing for a specific product, but then I sprouted some rubbish when I couldn't think of anything else to try and get the remaining marks.

What's the general opinion of the exam overall? Hard, medium or easy?
I found it hard, so I'm hoping for low grade boundaries. But I did like the start of the paper and the end questions, the middle parts of the exam are probably what screwed me over

can i say some thing about the induced fitting in that question

[Kabelan1]

i threw in the induced fit theory, everything i said for that answer was a load of bs.
