OCR Biology F212 (Molecules, Biodiversity, Food and Health)- 21st May 2012

I hope the examiners will learn from this for the Chemistry F322 Paper for Wednesday...

Yeah I doubt it.

I dont understand why no one write that similarity is that they both are polysaccahrides

and difference is that agarose has more than one component sugar where amylose is just contains alpha glucose

this is the right answer

did anyone else write that they give animals antibiotics for the farming one???????

for models i said specific active site and specific substrate
had no idea for why accpeted just put a random thing ?

hhahaha yes we meet again! did the same sunshine love you <3

Was it polysaccharide or cellulose???


This was posted from The Student Room's iPhone/iPad App

It was all on the syllabus, do not doubt that for one minute. They may have applied it to a different situation, like the elastic in the lungs for induced fit enzymes, but it was all in there. Some of the stuff was also 'how science works' or the green pages, which for some reason people believe not to be part of the syllabus.

non-competitive inhibitors

I thought that instead of cytoplasm fungi had mycelium, so i put protoctist

for model I said they cannot see enzyme catalysing reaction in a cell so you just using models to explain how it might work. could have been better if I had said it was just a hypothesis
for that one why favoured in exm hall I could remember my teacher talking about it bt just did not remember what was the reason I could even see her face lol!!
but later thought that she said something like substrate do not alwaz have complementary shape so enzyme have to change shape.
