Question

Sugar Cane produces 5,000 kg of sucrose per hectare of field. How much bioethanol can theoretically be produced from the sucrose via fermentation. Assume that the yeasts operate at 88% efficiency (i.e. 12% of the sucrose is utilized for cell maintenance and reproduction). Consider molecular equation for sucrose fermentation to solve this.

Answer 1

At first sucrose would be broken into glucose and fructose which are isomers of each other having molecular formula C₆H₁₂O₆​​​​​​. The glucose molecule ultimately breaks down into bioethanol and carbon dioxide in a number of steps. The overall reaction is only necessary to calculate the amount of bioethanol produced and is shown:
