Question

How would anaerobic conditions (when no O2 is present) affect the rate of electron transport and ATP production during oxidative phosphorylation? (Note that you should not consider the effect on ATP synthesis in glycolysis or the citric acid cycle.) a) Electron transport would be unaffected but ATP synthesis would stop. b)Electron transport would stop but ATP synthesis would be unaffected. c)Both electron transport and ATP synthesis would stop. d) Neither electron transport nor ATP synthesis would be affected.

Explanation / Answer

b)Electron transport would stop but ATP synthesis would be unaffected. Substrate level phosphorylation is still available to make ATP.
