Fermentation Investigation Planning As a culture of yeast is merged with solution of sugar, a reaction called fermentation occurs. As products, ethanol and carbon dioxide are produced, in form of liquid and gas respectively. The reaction follows this equation: Glucose solution + Yeast Carbon dioxide + Ethanol + (Energy) And as one of the products is in the form of gas, the volume of the product can be measured to demonstrate the difference of the reaction when certain …

…to accommodate the substrate any more. The analogy of this is to compare a key to a keyhole. If the keyhole has changed, the same key would not fit in any more, and the lock would not be unlocked. The same thing happens here, and fermentation could not continue after this has occurred. Also when the temperature is too low, the enzymes would not work because there is not enough energy for activities to happen.
