adenly cyclase is mentioned in the revision guide by Collins which is what the examiners use for reference so i think it should be ok? however in mark schemes adenylate cyclase is only mentioned
if you can rememeber adenylate use it , if not a nice marke could still give you adenyl/ it may be recognised short hand

Together the three rates for carbon dioxide must add up to 100%. i.e. 0.128 = 100%

To work out say stems and roots, take the number 0.051 and divide by 0.128 and multiply by 100.

So 0.051 / 0.128 = 0.398

0.398 * 100 = 39.8%

See if you can do the other one....
10. Good luck peeps

My last one

So hopefully the end of a-levels

Can't wait
