WebNov 2, 2024 · Gluconeogenesis and glycogenolysis are the two pathways essential for glucose homeostasis. Figure 5.1 illustrates the time frame and overlap of glycogenolysis and gluconeogenesis. These pathways are activated nearly simultaneously when the insulin to glucagon ratio becomes sufficiently reduced. Over time, the reliance on the pathways … WebJan 3, 2024 · Anaerobic (complete) glycolysis is a fermentation pathway. In anaerobic glycolysis the electrons in NADH produced in Stage 2 of glycolysis are used to reduce pyruvate, so that in the end, there is no consumption of O2 and no net oxidation of nutrient (i.e., glucose). A familiar anaerobic glycolytic pathway is the production of alcohol by …
