Consider the fatty acid which has 20 carbons (below).
- How many cycles of beta-oxidation are required? Briefly explain.
- How many acetyl-coA are produced. Briefly explain.
- How many NADH and FADH2 are produced from beta-oxidation (only) of this
molecule? - CORRECT ANSWER: A. 9 cycles are required. Each cycle removes 2-
carbon units, and the final cycle produces 2 acetyl groups.
- 10 acetyl-coA groups are produced. 2 are produced on the last cycle.
- 9 NADH and 9 FADH2 molecules are produced. Each round produces 1 NADH and
1 FADH2.
