, 2 An investigation was carried out to compare the aerobic respiration of different sugars
by yeast.
A suspension of yeast was used to produce three cultures, each one with a different sugar.
A control was set up that had a suspension of yeast cultured with water only.
The volume of carbon dioxide produced was measured.
The mass of yeast and the concentration of each sugar were controlled.
The graph shows the results of this investigation.
