If any of you have the OCR Biology A2 textbook you might be able to help me out....
Well pyruvate decarboxylase is used to remove a carboxyl group from pyruvate in the link reaction as it says on p89 which means it's obviously an enzyme that's present in animals.
But on p95, during the process of alcoholic fermentation it says: this reaction is catalysed by the enzyme by pyruvate decarboxylase (not present in animals)
Clearly the enzyme has to be though? Since it's needed in the link reaction? When I read it I assumed animals don't have the enzyme which is why alcoholic fermentation can't take place in animals but that's not the case now....
So any of you know whether I'm simply out of my mind stupid and am missing something simple or the books wrong? And if it is a typo then why can't alcoholic fermentation take place in animals?
