Complete aerobic oxidation yields about 30 to 32 ATP, compared with 2 from fermentation.
Theoretical maximum was 38 but updated estimates are about 30 to 32 because of transport costs and proton leaks. Roughly: glycolysis 2, Krebs 2, oxidative phosphorylation about 26 to 28.
Estimates vary with the shuttle used for NADH (glycerol phosphate or malate-aspartate). Proton leak lowers yield.
Example: the revised yield is about 30 to 32 ATP.
Complete aerobic oxidation yields about 30 to 32 ATP, compared with 2 from fermentation.
ATP Yield from Glucose is one of the 53 topics in Metabolism & Bioenergetics. It is rated Intermediate, so it suits learners who already know the core vocabulary. Related topics in this area include Cellular Respiration, Beta-Oxidation, Aerobic and Anaerobic Respiration.
P/O ratios are about 2.5 for NADH and 1.5 for FADH2.
Work through the Beginner topics in Metabolism & Bioenergetics first, such as Metabolism, Anabolism and Catabolism, ATP, then return to ATP Yield from Glucose. Intermediate topics assume the Beginner vocabulary.
The closest topics to ATP Yield from Glucose are Cellular Respiration, Beta-Oxidation, Aerobic and Anaerobic Respiration, NAD and FAD. Comparing them side by side is a good way to see how the ideas connect.
Read the summary and the in-depth section, then use the quick check on the interactive lesson for ATP Yield from Glucose. To practise the whole of Metabolism & Bioenergetics, use the Metabolism & Bioenergetics quiz.
ATP Yield from Glucose: Complete aerobic oxidation yields about 30 to 32 ATP, compared with 2 from fermentation. Cellular Respiration: The process of releasing energy from glucose to make ATP, using oxygen in the aerobic form. Read both side by side and note what each one explains.
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Cellular Respiration and explain the difference aloud. Finally, take the Metabolism & Bioenergetics quiz and come back to this page for any question you miss.
