Lactase Inhibitors

[VoiceofBetty]

Okay, this is a complete shout out to anyone who has ever done biology or is doing biology!!!! You guys are my last(?) hope!!!!LOL!!

For my AS coursework i have to do an experimant into the inhibition of the enzyme lactase using copper sulphate, and testing with glucose testing strips. I spent AGES doing it today and got no results - only the control worked!!!!!

SO, does anyone know what the results should look like for 'time taken to show traces of glucose/mins' for 0.02g, 0.04g, 0.06g, 0.08g and 0.1g of copper sulphate???!!!!!!

I would REALLY appreciate any help anyone could give me on this!! I'm gunna try the experiment again tomorrow, but if it doesnt work again i dunno what i'm gunna do!!! (i'm in the process of posting this cry for help all over the internet!)...

PLEASE HELP!!!!!

TTFN,

love and huge hugs,

Betty xox
