WebNov 2, 2024 · The process of $\beta$-oxidation supports gluconeogenesis in two major ways: The NADH and FADH 2 generated from $\beta$-oxidation is oxidized in the electron transport chain to produce ATP. This ATP provides the needed energy for glucose synthesis. It also supplies energy to the urea cycle for nitrogen disposal. WebTo bypass this irreversible reaction, gluconeogenesis makes use of two enzymes. First, the enzyme pyruvate carboxylase converts pyruvate into oxaloacetate, which requires the input of one molecule of ATP per molecule of pyruvate used. Next, the gluconeogenic enzyme PEP carboxykinase converts oxaloacetate into PEP, using one molecule of GTP per ...
