Derive the energy generated in terms of ATP molecules from the complete oxidation of a molecule of saturated fatty acid composed of fourteen (14) carbon atoms into carbon dioxide and water.
Note: Start with Beta -Oxidation of the fatty acid then proceed to KREBS’s Cycle with the ETS
In addition, two equivalents of ATP are lost during the activation of the fatty acid. Therefore, the total ATP yield can be stated as: (n - 1) * 14 + 10 - 2 = total ATP.
Source ATP Total
1 NADH × 2.5 ATP = 2.5 ATP
1 acetyl CoA × 10 ATP = 10 ATP
TOTAL = 14 ATP
