The main role of the yeast is to convert the sucrose into carbon dioxide (CO2) and ethanol. For example, when baking bread, the yeast ferments the sucrose within the dough and so CO2 and ethanol is released, causing the bread to rise and expand. It does this using enzymesAlso, during this fermentation process, because...
