I would say that catalase would have denatured significantly before 75 C. I think its optimum temperature is around 35-40 C and would start to denature at around 45 C ish. So if it was exposed to temperatures of 75 C, then yes, I'd say you should expect a decreased rate. I'm not certain as to its op...

Maggot Behaviour

Hey, I was wondering if anyone knew of any good sites or could give me any information on maggot behaviour that would be useful for my coursework. Subjects of particular interest are how blowfly larvae respond to light and information on phototaxis and kinesis. Thanks very much! :)

Anyone? Am I right on this or have I got the wrong end of the proverbial stick? XD

Oxygen Grabbers?

Does anyone know (or know where I can find) any information about organisms that are 'oxygen grabbers'? As far as I know, they are animals that live where there is a low partial pressure of oxygen (eg. up mountains). And their haemoglobin structure is somehow different in order to cope with less oxy...

Ahh, this was something I was confused about - fermentation can only occur with glucose? So all the other sugars would have to be converted to glucose before fermentation can take place, and other sugars cannot 'take glucose's place' in the reaction... is this correct?

How does a Sugar's Structure Affect Rate of Fermentation?

Hey everyone, I'm a little confused over this issue. I recently conducted an experiment as part of my A2 coursework investigating the rates of fermentation produced by various sugars (glucose, fructose, galactose, maltose and lactose). I got the results and they fitted the pattern I expected ie. glu...

Thanks for that scottyiu Well anyway I've decided to try to analyse these pH values as it seems trying to convert them to CO2 values has proved impossible >.> Or at least, at this level anyway I was also I little confused as to the enzymes involved. Are enzymes just needed to break down the di/polys...

A lot of people in my group are doing the experiment the way you described - I think I'm the only one doing it this way (on the teacher's recommendation I might add) and now am confused about how to use these pH values to work out carbon dioxide produced. I might have to just analyse the pH values t...

Need help with fermentation investigation!

Hey, this is the first time I'm posting here and I'm wondering if anyone can help me with a problem that's come up for my A2 level coursework. Technically it's biology but I guess it's part chemistry as well. Any suggestions greatly appreciated ^_^ I'm doing an investigation on how using various sug...
