This process results in the reduction of one molecule of ubiquinone via an (*) FADH2 intermediary, and its only membrane-bound step is the conversion of succinate to fumarate.
Fluoroacetate is a potent toxin because one of its metabolites blocks an important enzyme in this pathway. One of its intermediates is a precursor for both aminolevulinate and eventually porphyrins. The molecules consumed in this pathway are replenished by anaplerotic reactions. This process results in the reduction of one molecule of ubiquinone via an (*) FADH2 intermediary, and its only membrane-bound step is the conversion of succinate to fumarate. This process occurs within the mitochondrial matrix, and is followed by oxidative phosphorylation. For 10 points, name this pathway which contributes to the electron transport chain, an aerobic process central to cellular respiration.
