WebGlycogenolysis, which is first initiated by the breakdown of glycogen to free glucose-1-phosphate (G-1-P), eventually generates a net total of 31–33 ATP molecules from G-1-P … WebOverall, the glycolysis steps of the cycle produce 2 ATP molecules at a cost of 6 ATP molecules consumed in the gluconeogenesis steps. Each iteration of the cycle must be maintained by a net consumption of 4 ATP molecules. As a result, the cycle cannot be sustained indefinitely.
