In β-oxidation, the mitochondria oxidizes fatty acids and convert them into acetyl coA residues. In this process, one molecule of acetyl coA is produced per pass through the β-oxidation sequence, along with two pairs of electrons, and release of four protons, shortening the fatty acid by two carbon atoms. The protons released form NADH and FADH2 from NAD+ and FAD+, respectively.
How many net CO2 molecules are generated by the beta oxidation cycle given a fatty-acyl molecule of 24 carbons in length?
