In this article we will discuss about the fermentation of pyruvate to acetate to show oxidation-reduction balance. The oxidation-reduction reactions in any fermentation must be balanced. The total number of electrons in the products on the right side of the equation must balance the number in the substrates on the left side of the equation. To show oxidation-reduction balance the [...]
In this article we will discuss about the re-oxidation process of NADH during fermentation. NADH is not oxidized by the electron transport chain (i.e., the oxidative phosphorylation does not occur) in the absence of aerobic or anaerobic respiration because, in that condition, no external electron acceptor becomes available. Yet NADH generated in glycolysis during the oxidation of glyceraldehyde 3-phosphate to [...]
In fermentation, the energy conservation (ATP-synthesis) generally takes place by way of substrate-level phosphorylation and by way of decarboxylation of organic acids in certain cases. Way # 1. Substrate-level Phosphorylation and Fermentation: Substrate-level phosphorylation, is a mechanism by which high energy phosphate bonds from organic intermediates of the fermentation are transferred to ADP producing ATP. ATP synthesis via substrate-level phosphorylation [...]
