EFFECT OF DIFFERENT NUTRIENTS ON ANAEROBIC RESPIRATION OF YEAST

Asked by Ai Fang | Aug 12, 2008 | KS2 Level > Biology > Coursework

Ai Fang asks:

Why distilled water,lactose and starch solution do not used up by respiration of yeast and did not released any gas?

etutor answers:
I don't really understand your question. Is it asking about different substrates for anaerobic respiration? The yeast would obviously need some form of carbohydrate (so distilled water is no good). I would expect a small amount of gas with lactose and starch, although the yeast may not have the correct enzymes to break these down.
