Why are you able to evaluate CO2 production as a measurement of alcoholic fermentation?
What does it tell you about alcoholic fermentation?
Homework Answers
From one mole of glucose, in fermentation two moles of ethanol and two moles of carbon di oxide will be produced.
The reaction is:
For every 180 grams of glucose, 88 grams of CO2 and 92 grams of Ethanol will be produced, on the basis of this CO2 is using as the measurement for alcholic fermentation.
By using simple cross equation we can find the Ethanol production.
where x= amount of CO2 grams/mol and a = appropriate ethanol quantity
Add Answer to:
Why are you able to evaluate CO2 production as a measurement of
alcoholic fermentation?

What are the four possible results of a fermentation experiment and what does each indicate? What does a pH indicator tell you? Which pH indicator did we use in fermentation tubes? Explain why E. coli would ferment glucose to acid/gas result while Pseudomonas does not? Why would a bacterium oxidize a molecule instead of fermenting it? If an inoculated OF tube turns yellow and DOES not have mineral oil on top – what process(es) caused the color change?

4) In the absence of O2 fermentation will occur, why?.....what does it yield that the organism needs from these reactions? Why? 5) Gluconeogenesis is the production of glucose from non-carbohydrate precursors. a. What distinguishes glycolysis from gluconeogenesis?
