$13.$ When a methanogen is using methanol $\backslash ((\backslash$mathrm$\{$CH$\}3\backslash$mathrm$\{$OH$\})\backslash )$ as its electron acceptor and $\backslash (\backslash$mathrm$\{$H$\}\_\{2\}\backslash )$ as its electron donor, for each methane generated, how many CH $3$ OH and H $2$ molecules are used? How does a methanogen doing this process generate its energy? If all the H$2$ was used up and the cell only had methanol available, what adjustments would the methanogen make to continue generating energy? $(14$ points$)$
