Description: Two acetyl-CoA molecules enter the cycle, one at the citrate synthase step, and the second at the malate synthase step. The reactions catalyzed by isocitrate lyase and malate synthase bypass the three citric acid cycle steps between isocitrate and succinate so that the two carbons lost in the citric acid cycle are saved, resulting in the net synthesis of oxaloacetate.
