Question

Which is FALSE: During the oxidation of pyruvate through the PDH reaction and the Krebs Cycle-

Select one:

a. three oxygen atoms and nine hydrogen atoms are added to the substrates in various steps

b. the number of hydrogen pairs transferred to electron carriers equals the number of hydrogen atoms that are present in pyruvate

c. the number of oxygen atoms released as CO2 exceeds the number of oxygen atoms present in pyruvate (WRONG)

d. the number of carbon atoms released as CO2 equals the number of carbon atoms present in pyruvate

e. all the answers are correct

For some reason the answer is not E or C... im confused

Explanation / Answer

Answer: - Option- "e"-all the answers are correct.

Explanation: - Nothing is false,because during the oxidation of pyruvate through the PDH reaction and the Krebs Cycle Pyruvate from glycolysis is converted to Acetyl Coenzyme A (acetyl CoA) . Thev following is the reaction involved:

Pyruvate + CoA + NAD+ ——> CO2 + acetyl-CoA + NADH + H+
