PMS-pathway control state

Description

PMS

PMS: Pyruvate & Malate & Succinate.

MitoPathway control: CI&II

Pyruvate (P) is oxidatively decarboxylated to acetyl-CoA and CO2, yielding NADH catalyzed by pyruvate dehydrogenase. Malate (M) is oxidized to oxaloacetate by mt-malate dehydrogenase located in the mitochondrial matrix. Condensation of oxaloacate with acetyl-CoA yields citrate (citrate synthase). This documents an additive effect of convergent CI&II electron flow to the Q-junction, with consistent results obtained with permeabilized muscle fibres and isolated mitochondria (Gnaiger 2009).
