O What is the net gain in ATP for ß-oxidation of palmitic acid (a sixteen-carbon fatty acid)? ANSWER: 107 ATP EXPLANATION: , palmitic acid is activated to produce a 16-carbon acyl-CoA. The activation step consumes one ATP. -carbon fatty acyl-CoA will undergo seven ß-oxidation _ls. Each of the first six spirals of ß-oxidation produces acetyl-CoA, one NADH, and one FADH₂. The final of the spiral produces two acetyl-CoA, one NADH, one FADH₂. The acetyl-CoA are processed through itric acid cycle, producing ATP and more reduced zymes. The NADH, and FADH₂ formed in ß- ation, and the NADH, and FADH₂ formed in the citric cycle undergo oxidative phosphorylation. Because ATP was consumed in the activation reaction, it is acted when calculating the net gain of ATP. ß- ation of a sixteen-carbon fatty acid, on average, results met gain of 107 ATP. fatty acyl-CoA with 16 carbons CHÍCH CH-CH-CH-CH-CH-CH-CHCHCHCHCHCHCHC–CaA fatty acyl-CoA with 4 carbons O For more details: See chapter 15 part 11 video or fatty acyl-CoA with 14 carbons CHCHÍCH CHÍCH CHÍCH CHCHCHCH,CH,CHC–CoA fatty acyl-CoA with 10 carbons CHÍCH CHCHCH CHÍCH-CH-CHC–CHA fatty acyl-CoA with 8 carbons 9 CHCHCH;CH CHCHCH2–Cas acetyl-CoA fatty acyl-CoA with 12 carbons CH;CH_CH,CH,CH,CH,CH,CH,CH,CH,CH;C —CeA fatty acyl-CoA with 6 carbons CH,CHỊCH,CH,CHC–CoA CH₂CH₂CH₂C-CoA) -‒‒‒‒‒ Total: 8 acetyl-CoA Citric Acid Cycle Subtract one ATP that was used in the activation reaction 8 ATP 22.5 ATP 0 77.5 ATP -1 ATP acetyl-CoA FADH₂ acetyl-CoA FADH₂ + NADH acetyl-CoA+FADH₂ NADH acetyl-CoA+FADH₂ + NADH NADH acetyl-CoA FADH₂ + NADH acetyl-CoA+ FADH₂ NADH acetyl-CoA+FADH₂ Oxidative Phosphorylation 1.5 ATP 1 FADH₂ 2.5 ATP 1 NADH NADH 8 FADH₂ + 24 NADH Totals: 15 FADH₂ 31 NADH

15.22) What is the net gain in ATP for ß-oxidation of palmitic acid (a sixteen-carbon fatty acid)? ANSWER: 107 ATP EXPLANATION: First, palmitic acid is activated to produce a 16-carbon fatty acyl-CoA. The activation step consumes one ATP. A 16-carbon fatty acyl-CoA will undergo seven ß-oxidation spirals. Each of the first six spirals of ß-oxidation produces one acetyl-CoA, one NADH, and one FADH₂. The final cycle of the spiral produces two acetyl-CoA, one NADH, and one FADH₂. The acetyl-CoA are processed through the citric acid cycle, producing ATP and more reduced coenzymes. The NADH, and FADH₂ formed in ß- oxidation, and the NADH, and FADH₂ formed in the citric acid cycle undergo oxidative phosphorylation. Because one ATP was consumed in the activation reaction, it is subtracted when calculating the net gain of ATP. B- oxidation of a sixteen-carbon fatty acid, on average, results in a net gain of 107 ATP. fatty acyl-CoA with 16 carbons | CHỊCH CHỊCH,CH,CH_CH,CHCH,CH,CH,CH,CH,CH,CH,C –CoA fatty acyl-CoA with 4 carbons fatty acyl-CoA with 14 carbons | CH,CH;CH;CH;CH,CH;CH,CH,CH;CH;CH,CHỊCH,C—COA fatty acyl-CoA with 10 carbons CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂C For more details: See chapter 15 part 11 video or fatty acyl-CoA with 12 carbons CHCHCH,CH,CHCHCH CHÍCH CHÍCH,C–Cos fatty acyl-CoA with 8 carbons CH,CHỊCH;CH,CH_CH,CH,—CoA fatty acyl-CoA with 6 carbons | CH,CH;CH;CH;CH,C…CA acetyl-CoA CH₂CH₂CH₂C-COA -‒‒‒‒ Total: 8 acetyl-CoA Citric Acid Cycle Subtract one ATP that was used in the activation reaction 8 ATP 22.5 ATP 77.5 ATP -1 ATP acetyl-CoA 23 acetyl-CoA FADH₂ + NADH acetyl-CoA acetyl-CoA acetyl-CoA FADH₂ NADH acetyl-CoA acetyl-CoA FADH₂ + NADH 1.5 ATP 1 FADH₂ FADH₂ + NADH 2.5 ATP 1 NADH FADH₂ NADH FADH₂ + NADH Totals: Oxidative Phosphorylation 15 FADH₂ 31 NADH FADH₂ + NADH 8 FADH₂ + 24 NADH
