Stoichiometry of glycolysis in yeast lab problems

[jiunshan]

I had carried out a lab session and I am facing a big problems which I cant get through, I hope somebody here can help me.

 

While I was getting UV absorbance at 510 nm for glucose standard curve, I get a negative reading for one of the tube. Is this possible? Why?

 

somehow, I get negative reading for [ethanol] produced and [glucose] catabolised. Is that means no ethanol being produced nor glucose being catabolised?

 

I had attached my lab report with this thread, hope someone can answer my problems. Thanks a lot!!!

This is too far above my level of knowledge to be of much assistance. However, I do believe you should change the section title at the end from "Bibliography" to "References." This is a rather topical bit of feedback, but I generally don't see the the term bibliography much outside of high school. Check what's appropriate in your department first before making changes though.

 

Good luck in all of your studies.

Please let us know what you find out. I'd be curious to know whether a negative result is or is not possible.
