WebDuring conditions of increased protein metabolism following ingestion of a high protein diet, or during fasting, when muscle protein is degraded to supply carbon skeletons for glucose production (gluconeogenesis), the urea cycle operates at an increased rate to eliminate excess nitrogen as urea. 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.
