PM-pathway control state
Description
PM: Oxidative decarboxylation of pyruvate is catalyzed by pyruvate dehydrogenase and yields acetyl-CoA. mt-Malate dehydrogenase located in the mitochondrial matrix oxidises malate to oxaloacetate. Condensation of oxaloacate with acetyl-CoA yields citrate (citrate synthase). 2-oxoglutarate (Ξ±-ketoglutarate) is formed from isocitrate (isocitrate dehydrogenase).
Abbreviation: PM

Discussion
- Pyruvate alone is not an ETS competent substrate state in most mt-preparations, since acetyl-CoA accumulates without the co-substrate (oxaloacetate) of citrate synthase.
- Malate Alone is not an ETS competent substrate state in many mt-preparations, since oxaloacetate accumulates without the co-substrate (acetyl-CoA) of citrate synthase.
