Same as the Citric Acid Cycle except for reactions catalyzed by Isocitrate Lyase* and Malate Synthase*.
ReactionEnzyme
Oxaloacetate + Acetyl CoA + H2O -> Citrate + CoACitrate Synthase
Citrate -> IsocitrateAconitase
Isocitrate -> Glyoxylate + SuccinateIsocitrate Lyase*
Glyoxylate + Acetyl CoA + H2O -> Malate + CoAMalate Synthase*
Malate + NAD+ -> Oxaloacetate + NADH + H+Malate Dehydrogenase
