Investigating respiration in yeast I am investigating the respiration of yeast and finding the best conditions for producing carbon dioxide by breaking down glucose using yeast as the catalyst. Affecting factors There are factors that could affect the outcome of my investigation such as:> The temperature> The amount of yeast> Another factor that could affect our investigation is the percentage of glucose in the yeast.
