Accordingly, (page 592 of Leboffe & Pierce 3E), what kind of fermentation process does S.cerevisiae undergo? Cells use oxygen to break down the sugar glucose and store its energy in molecules of adenosine triphosphate (ATP). However, the rate of fermentation gets faster as the pH decreases since the enzymes are more suitable to work at acidic pH.

Some types of prokaryotes are facultatively anaerobic, which means that they can switch between aerobic respiration and fermentation, depending on the availability of oxygen. 3. In this article, we'll take a closer look at anaerobic cellular respiration and at the different types of fermentation. Anaerobic cellular respiration is similar to aerobic cellular respiration in that electrons extracted from a fuel molecule are passed through an electron transport chain, driving synthesis.
