This is me done too. One word of advice....some of the stuff on here needs checking for verification but its been a great help for answers and throwing out suggestions and knowing there are other people in the same boat! Best of luck to anyone else still doing it. Don't stress out too much. Steen x

TIs my understanding. But if you're doing what im doing and it sounds like you are, it says you are given the suspension so you dont have to worry about it too much

Re: the decomposition of methylene blue; this will be for solid material and the decomposition temperature is much higher than boiling water--which is probably about as high a temperature that will be sampled in this experiment. Methylene blue melts and 100-110 C, btw. The stuff we were given was i...

Sensible. I am a bit of an odd ball (further maths) But i only ask because different enzymes go at different points so theoretically the cell could be clear but still 'living' just incapacitated. It states in our brief thing that it's the enzymes involved in respiration and according to the faithfu...

Nice! so 60-70 was pretty much the right bracket then!

You're testing to see if the yeast is alive and so it doesnt matter whether its anaerobic or aerobic but interesting theory - had to think about it for a while!!

I've done it as a separate section but just before the method as it affects the method. But it's an element of choice really

My first set of prelims didnt work cos the methylene blue was too dark for the amounts of yeast and glucose I was using - so It wasnt being turned colourless so I used more (glucose and yeast) in effect making the methylene blue more dilute. Mine took quite a while to go colourless - however if they...

My prelims suggested between 60 and 70. But some websites are quoting mid-40's but this may give you a rough guide. It's probably worth thinking about why your prelims failed in order to cover this for the actual plan - then you can include them anyway. And Im not sure what you mean by the theory so...
