Question

Calculate the ATP production of 6:0 fatty acid. Can fatty acid catabolism occur without oxygen?

Answer 1

catabolism wont occur without oxygen

the ATP production of 6:0 fatty acid ( caproic acid )

in beta oxidation 2 FADH_{2 ,} 2 NADH molecules

Citric acid cycle:
(3 turns; once for each 2-carbon fragment)
- 3 FADH2 (1FADH2 per turn, 3 turns=3)
- 9 NADH (3 NADH per turn, 3 turns=9)
- 3 GTP (1GTP per turn, 3 turns=3)
Total:
- 5 FADH2
-11 NADH
- 3 GTP

The NADH, FADH2, and GTP undergo oxidative phosphorylation in the electron transport chain
to yield:
2.5 ATP molecules per NADH
1.5 ATP molecules per FADH2
1.0 ATP molecule per GTP


Thus, 38 ATP molecules are synthesized without undergoing ETC .
