Question

1. Give the number of ATP made from the breakdown of a 12C fatty acid to that of two molecules of glucose. Explain where the ATP comes from when catabolizing your lipid. Which made more ATP, the fatty acid or the two molecules of glucose?

Answer 1

112c - fatty acid 2 ATP required for fatty acid activation. B oxidation of fatty-Cou produces - 5 Cycles will be required 3 6 Acetyl A i 2 Acetyl coa releases 5 FADH₂ 5 NADH THA at 5th Cycle) I Alety CoA produces I FADH₂ I NADHTHA - 10 ATP - 1.5 ATP 2.5 ATP * 10x6 = Go ATP 1.5x5 + 70 5 ATP 205x5 = 12.5 ATP 80 АТР - 2 ATP (used) - 78 ATP produced 1 glucose produces - - Q ATP 2 Pyruvate 2 Acetyl LOA t 2 NADHTHt QNADH THE

1 glucose produces - Glycolysis - Q ATP + 2 NADH+H* 2 Perwate Acetyl coA QNADH THE 2 citric acid cycle 2 ATP + 6 NADHTH & + 2F A DH&K ( because 2 pyruvate) 4ATP + lox2-5 + 2x 105 1.5 42.5 data = 4 + 25 taken from +3. Lehninger book. = 32 ATP If we consider & INADH2H produces 3 ATP and 10 IFADH2 – QATP then, 4 + lox3 + 2x2 = 4 +30+4 = (38 ATP) 2 glucose make 7 32x2=64 or 38x2 = 76 ATPS Both are less than tatty acid.
