A fermentation process was carried out with a yeast in a chemically defined medium containing glucose (C6H12O6) as a carbon source aiming at the production of ethanol (C2H6O). For the evaluation of the process, samples were taken at different times of cultivation and the experimental results are shown in the Table below. Based on the experimental results, one can: a) Calculate the overall substrate-to-cell conversion factor
