From the cellular respiration and fermentation lab, why are the yeasts breaking down the sugars? the yeast are breaking down the sugars to produce ATP why will yeast metabolize monosaccharaides at a faster rate than disaccharides yeast will metabolize monosaccharides faster than dissacharides because dissacharides are more complex sugars and must first be broken down into its monosaccharide subunits, therefore taking more time how many NET molecules of ATP are created during aerobic respi...
