1. What is the difference between substrate phosphorylation and
oxidative phosphorylation?
2. Starting with glucose and ending with pyruvate, list, in
sequence, the initial, intermediate,
and final metabolites in the glycolytic pathway. Show, at the
appropriate steps, where ATP is
consumed and/or produced and where NADH is consumed and/or
produced.
3. Starting with pyruvate, draw the Citric acid cycle showing all
the intermediates (by name if
not by structure). Show, at the appropriate steps, where ATP is
produced and/or consumed,
where NADH is produced and/or consumed, where FADH2 is produced
and/or consumed, and
where CO2 is released.
4. Explain, for both a yeast cell and for a skeletal muscle cell,
where fermentation happens, how
it happens, and why it happens.
