Transcribed Image Text:In the cellen there is glucose that is
fermented. You should follow the reaction
paths the glucose molecules can take,
through glycolysis and "Mixed acid
fermentation" to the end products you see in
the reaction overview. From one glucose are
formed 2 phosphoenolpyruvate. Then there
are several possible paths. In the case of
phosphoenolpyruvate, pyruvate and
acetylCoA, the pathways divide and one
molecule can go one way while the other goes
another way. In the task, acetate is a given
end product, but which is the other for the
summation reaction to be both stoichiometric
and redox balanced?
