Total (5 points) (20 points) (25 points) (15 points) (20 points) (15 points) (100 points: for two of the following 6 cofactors, draw the business ends for both forms listed. R: hydride acceptor/donor used to transfer electrons in the cell for oxidation and reduction reactions. N: an electron sink (we saw it used for -decarboxylation) R2: redox cofactor (we saw it attached to lys used in the pdh complex) Hs: used to find co2 for carboxylation reactions. R: used as a h acceptor/donor for electron and h+ transfer. Zymomonas mobilis is an ethanol-producing bacterium that yields an unusually high yield of ethanol from glucose (92-94%). Not all the reaction above are shown, but you can follow it through in more detail from the class notes.
