Q1medium

How many net ATP molecules are produced during the complete aerobic oxidation of one glucose molecule, assuming the Malate-Aspartate shuttle is active and 1 NADH yields 2.5 ATP, while 1 FADH2_2 yields 1.5 ATP?

Q2easy

Which of the following stages of aerobic respiration produces ATP directly via substrate-level phosphorylation?

Q3medium

If a cell uses the Glycerol-3-Phosphate shuttle for cytoplasmic NADH, what would be the total ATP yield from the 2 NADH molecules produced during glycolysis, assuming 1 NADH = 2.5 ATP and 1 FADH2_2 = 1.5 ATP?

Q4easy

How many molecules of CO2_2 are released during the complete aerobic oxidation of one molecule of glucose?

Q5medium

Which of the following statements about the Electron Transport System (ETS) in the context of the Respiratory Balance Sheet is INCORRECT?

Q6hard

Considering the older convention where 1 NADH yields 3 ATP and 1 FADH2_2 yields 2 ATP, and assuming the Malate-Aspartate shuttle, what is the total theoretical ATP yield from one glucose molecule?
