Two related species metabolize glucose using the exact same pathways (glycolysis, citric acid cycle, oxidative phosphorylation).
Experiments show, however, that species A generates only 83% of the ATP compared to species B when provided with the same amount of glucose. What could be a potential reason for this outcome
The correct answer is - there is a 12-Carbon ring in ATP synthase of species A whereas species B contains a 10-carbon ring.
Explanation:
ATP Synthase is a protein complex that catalyzes the transfer of the protons down the gradient build by the action of the electron system in the mitochondria and makes ATP from ADP molecules.
The higher number of carbon in ATP synthase will require more protons to rotate to produce 3 ATP in this process so, if species A has more carbon present it will take more protons and able to produce only 83% of ATP compared to species B.
