Story: In 1978 Fiat introduced a car that could run entirely on ethanol. In the United States corn is milled and broken down into starch, fiber, protein and more. Corn is roughly 20% starch, 35% hemicellulose and 14% cellulose. Following saccharification (the breakdown of complex carbohydrates), Saccharomyces cerevisiae (yeast) catabolize the sugar substrates to make ethanol.    Scenario: Generation of ethanol  1. For this  scenario, list the pathways involved in the correct order.    2. For this scenario, indicated if it is: chemoorganotroph                 chemolithotroph         phototroph                  autotroph.                     heterotroph                 aerobic                          anaerobic
