Answer to Question #190633 in Biochemistry for Hazel Balanon

Question

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

Answer 1

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.

...

Energy yield.

Source ATP Total

1 NADH × 2.5 ATP = 2.5 ATP

(Theoritically

3 ATP)

1 acetyl CoA × 10 ATP = 10 ATP

( Theoritically

12 ATP)

TOTAL = 14 ATP
