Summary Introduction

To describe: The number of ATP molecules that would be produced by the oxidation of fatty acid that has 16 carbons.

Introduction:  The fatty-acid oxidation (β-oxidation) is a metabolic pathway. In this pathway, the fats are metabolized to release energy. The oxidation of fatty acid continually occurs, while it does not become a main source of energy until the animals’ carbohydrate resources are exhausted. The oxidation of fatty acid mainly occurs in peroxisomes in plant cells and mitochondria in animal cells.

Explanation of Solution

During the catabolism of fats, one molecule of ATP is used in each round of beta-oxidation and produces one molecule each of NADH and FADH2. Seven rounds of beta-oxidation would convert the fatty acid into eight molecules of acetyl-CoA for a 16-carbon fatty acid. In the Krebs cycle, the oxidation of each acetyl-CoA produced 10 molecules of ATP.

Thus, the overall yield of ATP from 16-carbon fatty acid would be a net gain of 21 ATP from seven rounds of beta-oxidation (gain of 4 ATP per round – 1 per round of prime reaction) + 80 ATP from the oxidation of 8 acetyl-CoA = 101 ATP molecules.
