Cellular Respiration: Alcoholic Fermentation. Introduction Some fungi, as well as saccharomyces cerevisiae, also known as “baker’s yeast,” shift from cellular respiration to alcoholic fermentation when the amount of oxygen is diminished. The starting compounds of fermentation derive from starch which is converted to glucose and fructose.. Jaxon smith obituary nj

The yeast simply switches from aerobic respiration (requiring oxygen) to anaerobic respiration (not requiring oxygen) and converts its food without oxygen in a process known as fermentation. Due to the absence of oxygen, the waste products of this chemical reaction are different and this fermentation process results in carbon dioxide and ethanol.6.1: Cellular Respiration.
