1. What are the steps involved (in order) in the conversion of pyruvate to acetyl-CoA?
2. How many net ATP is yielded during converting one glucose molecule into CO2 using Glycolysis, PDH and CAC?
3. What is the name of the enzyme that transports the pyruvate into the PDH?
4. Provide the OVERALL reaction (net equation) of Citric Acid Cycle.
5. Write the OVERALL reaction (net equation) catalyzed by pyruvate dehydrogenase complex.
6. What is the step-wise chemical mechanism of PDH?
7. Pyruvate dehydrogenase complex and citric acid cycle together can oxidize pyruvate in CO2. During this process (from pyruvate to CO2),
