OCR Biology F212 May 2012 Questions (not actual paper)

Here's my attempt as trying to create the paper :redface:, the wording of the questions are minimal but should be enough for you to identify the question. The marks are guesses and the questions are not in order, also there's quiet a few questions missing so post them below and I'll add them and hopefully when someone manages to get the paper they'll post it.

Label active site and substrate [2]
Why are the induced fit and lock and key called models? [1]
Why induced fit is favoured [1]
Type of carbohydrate [1]
Coughing and smoking question [7]
Describe relationship shown in graph about smoking [4]
Name 2 diseases associated with smoking [2]
Describe how to measure reducing sugar conc. without colorimeter [5]
Described test for non reducing sugar [3]
Bat q about discontinuous and continuous variation [7]
What can farmers do to increase productivity [1]
Percentage change calculation [2]
Control letter L [1]
amylose similarities and differences [2]
breeding of sheep [3]
why enzyme is flexible [2]
why bacteria cannot take up lactose [1]
why enzymes can not form less than 1 degrees [2]
Conservation of fish [4]
Why inorganic fertilizer decreases biodiversity [3]
Name genus [1]
Fill in Protoctista, Animalia and Plantae [3]
How do protoctista feed [1]
Test tube B used as a control [1]
How to make exp. More reliable [3]
Q on 3 domains [3]
Name new species [1]
Fill in biodiversity keywords last q [6]

you forgot about the question less than 1 degrees ? and the question on why bacteria can not take up lactose directly

yep what was the question and how many marks was it?

why bacteria cannot take up lactose (1)
why enzymes can not form less than 1 degrees(2) i think

try making an unofficial mark scheme cause these are all the questions :biggrin:

Thanks added, a unofficial mark scheme is much harder to create plus I'm not sure if my answers are correct and other will disagree with them etc.

Anyone know what the grade boundaries usually are for AS biology? x

Wasn't it bacteria breaking down Agrose? I don't remember lactose...

these are all the questions :wink: only one thing you forgot which was one mark was the letter thing i put L?
can you make a mark scheme cause these are all the question

Yeah, that's the question which I wrote 'Suitable Control' for and tbh Biology isn't like Chem or Maths it's hard to make a mark scheme for it, people can write so many different answers to the same question

Anything between 75 - 88 hopefully but any mark that gets me an A will be fine but we'll all have to wait and see till results day and good luck to you, hope you get the result your looking for

for enzymes different was it correct to say different active site ?

yes and you could have said that one enzyme might have a coenzyme attached to it
