I am trying to answer the question below, and I am guessing the reason lactate has a lower Km is that it is better able to accept electrons than ethanol. Is this correct? If so, what makes lactate a better electron acceptor? Any help is greatly appreciated!
"ethanol is a very poor substrate for LDH
Would you expect the Km for ethanol to be higher or lower than that for lactate? Justify your answer with reference to the active site structure and the structures of lactate and ethanol. Include sketches of the structures of lactate and ethanol at pH 7.0"
