When palmitate (C16) completely oxidized, net yield is 129 ATP.

There are 7 β-oxidation cycles for palmitate to completely oxidazed.

One β-oxidation (beta-oxidation) cycle produces 1 NADH, 1 FADH2, and 1 acetyl CoA (sea the picture below).

For 7 cycles: 7 NADH, 7 FADH2, and 8 acetyl CoA.

NADH and FADH2 enter Electron Transport System (ETS) cycle to generate 3ATP and 2ATP respectively.

Acetyl CoA enter into tricarboxylic acid cycle (TCA) and each CoA gives 12 ATP.

7 NADH = 7 x 3 = 21 ATP

7 FADH2 = 7 x 2 = 14 ATP

8 acetyl-CoA = 8 x 12 = 96 ATP

Net yield of ATP = 21 ATP + 14 ATP + 96 ATP - 2 ATP (used during conversion of palmitic acid into palmitoyl CoA)

Net yield of ATP = 129 ATP
