Gluconeogenesis (what are the ATP consuming steps?)

Web2. All gluconeuogenesis precursors must be converted to OAA for the process. In glycolysis: PEP is converted to pyruvate by pyruvate kinase in an irreversible reaction. So in gluconeogenesis: conversion of pyruvate-->PEP consists of two steps: 1a. Pyruvate-->oxaloacetate (OAA) by pyruvate carboxylase. **1b. 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. WebHow many ATP does gluconeogenesis use?
