Draw out a more detailed interconnected pathway of how anaerobic Alphaproteobacterium from the Rhodospirillaceae family will generate reducing equivalents NAD(P)H utilizing the following cycles: TCA Cycle (Tricarboxylic Acid Cycle or Krebs Cycle): Succinate, one of the components in the growth medium, can be metabolized through the TCA cycle. This cycle generates NADH and FADH2, which can contribute to the production of reducing equivalents. Succinate --> TCA Cycle --> NADH + FADH2 DMSO Reduction: Dimethyl sulfoxide (DMSO) in the growth medium can potentially serve as an electron acceptor. Reduction of DMSO may generate NADH or other reducing equivalents. DMSO Reduction --> NADH Hydrogenases: The presence of 1% H2 in the headspace suggests that the bacterium may possess hydrogenases, enzymes that can catalyze the reversible conversion of molecular hydrogen. This can lead to the generation of reducing equivalents. H2 --> Hydrogenase --> NADH
