In this experiment different concentrations of sucrose were tested to determine which leads to the most respiratory activity in yeast. Yeast is a heterotrophic anaerobic fungus which lacks chlorophyll. Yeast is used commercially to ferment the sugars of wheat, barley, and corn to produce alcohol, and in the baking industry to raise or expa ...

... + 4 CO2 sucrose + water (yields) ethanol + carbon dioxide In order to determine what concentration of sucrose and water leads to the most respiratory activity, ten large test tubes were set with different concentrations by the process of serial dilution. The first test tube was filled with 40 ml of 60% sucrose solution. Then, the nine remaining test tubes were serially diluted, so that the sucrose concentration ranged from 30% to 0.12%. The hypothesis in this expriment w ...
