Web2 nov. 2024 · The full β -oxidation spiral consists of four steps that result in the generation of acetyl-CoA, NADH, and FADH 2 for each cycle (figure 5.9). The NADH and FADH 2 generated will be oxidized in the ETC to produce ATP. The acetyl-CoA can be oxidized in the TCA cycle, but more likely it will be used in ketogenesis. Gluconeogenesis is, in simple terms, glycolysis in reverse. Where levels of glucose are low, such as in a diabetic hypoglycemic episode or during starvation or long-term fasting, the body can make glucose from non-carbohydrate sources.
