In this experiment, the fermentation of yeast using table sugar (sucrose) and honey (fructose and glucose) was compared to the fermentation of yeast using Equal® Spoonful (aspartame). Both table sugar and honey contain simple sugars which yeast utilize to produce energy in the fermentation process.

Describe an experiment that you could use to test if a different type of sugar would give the same results ... During fermentation baker's yeast breaks glucose into ethyl alcohol and carbon dioxide. C6H12O6 =====> 2C2H5OH + 2CO2; This process only yields 2 ATP per glucose molecule.

In the absence of oxygen, yeast will switch to an alternative pathway that does not require oxygen. The end products of this pathway are CO2 and ethanol. The first pathway yields a lot more energy per sugar molecule consumed, and so it is the "preferred" pathway if oxygen is present.

Investigation of fermentation provides opportunities for introductory level students to study metabolism and develop skills used in experimentation. I describe in this article a simple, inexpensive apparatus for measuring yeast fermentation and suggestions for its use in investigative studies.

The yeast experiment page, Yeast_exp.htm, shows fermentation in action. Yeast added to soda produces carbon dioxide that blows up the balloon. The balloon keeps out oxygen. If oxygen is present then the balloon stays limp.

You don’t need to understand the science of fermentation to make good spirits and liqueurs in the home unless you want to experiment with the fermentation system, i.e., fermenting larger volumes or higher alcohol levels. ... Yeast is a living organism very similar to the individual cells in our own bodies. It is easy...
