Question
Which of the following set of answers correctly indicate which of the next statements are true and which ones are false?
1)Pyruvate is converted into acetyl CoA in the cytosol.
2)The citric acid cycle (Krebs cycle) generates FADH2 and NADH and GTP by substrate level phosphorylation
3)The citric acid cycle (Krebs cycle) is a series of oxidation reactions that removes carbon atoms that originally come from substrates, like glucose in the form of CO2
4)The formation of Acetyl CoA is a complex mechanism that release CO2 and NAD+ from NADH
Explanation / Answer
1)Pyruvate is converted into acetyl CoA in the cytosol.----------> FALSE (acetyl CoA is formed in mitochondria).
2) The citric acid cycle (Krebs cycle) generates FADH2 and NADH and GTP by substrate level phosphorylation -----> TRUE
3)The citric acid cycle (Krebs cycle) is a series of oxidation reactions that removes carbon atoms that originally come from substrates, like glucose in the form of CO2 ---------> FALSE (only two carbons are removed in the form of CO2, the remaining is converted into ATP).
4)The formation of Acetyl CoA is a complex mechanism that release CO2 and NAD+ from NADH ------------> FALSE (along with aceyl CoA, CO2 and NADH are formed not NAD+)
