- 50
- 129
Answer ✔ (d) 129
Explanation: Palmitic acid (16 + 1 carbons) is a fatty acid and it can form 8 acetyl CoA units. For this it must complete 7 cycles of β oxidation ( each cycle removes 2 carbon atoms from fatty acid chain in the form of acetyl CoA). Each cyce of beta oxidation generates 5 ATPs. Each TCA cycle generates 12 ATPs (from acetyl CoA).
Total 7 cycles of beta oxidation = 7 × 5 = 35 ATPs.
Total 8 cycles of TCA = 8 × 12 = 96 ATPs. total ATPs = 96 +35 = 131.
2 ATP molecues utiised in the β-oxidation. net molecules obtained from palmitic acid →129 ATPs.
