Practical use for yeast fermentation
WebAbstract Yeast contains an enzyme, called catalase, that acts as a catalyst for the reaction that breaks down hydrogen peroxide into oxygen and water (2H 2 O 2 2H 2 O + O 2).Safety note: oxygen is a highly reactive gas, adult supervision recommended for this project. For your background research, be sure that you understand substrate, catalyst, reaction rate, … WebYeast activation and the initiation of fermentation are triggered by hydration, from either water or some other liquid, and the presence of a food source. Fermentation ends at 140 degree F during baking when heat kills the yeast. (Fermentation can end earlier, if the yeast is killed by other factors.)
