Document Summary

Metabolism: what is a redox reaction, the addition or removal of electrons to a molecule via an electron carrier and an enzyme. Nad+, nadh(freely diffusible); cytochrome c(membrane bound: how can nad+ act as an electron carrier, accepts electrons from a donor, via an enzyme. Dehydrogenases: how can nadh act as an electron carrier, reacts with and reduces a substrate by donating electrons, via an enzyme. How is each considered an energy storage molecule: poly-b-hydroxybutyrate, glycogen, elemental sulfur. What role would a methanogen play in helping syntrophomonas ferment butyrate: a cooperative, symbiotic relationship in which two or more microbes work together to degrade a compound. Why is it necessary for pyruvate to be reduced to lactate or other fermentation product: anaerobic respiration, perfectly analogous to glycolysis, the atp is generated via slph, which produces pyruvate x2. It is reduced to fermentation products in order to regenerate nad+.
