What would be the ATP yield for palmitate; a 16 carbon fatty acid?
-Saturated; even numbered fatty acid
-Process requires input of 2 ATP to activate.
Just tell me the number and how you came up with that answer.

For a 16 carbon FA, the first seven cycles of β-oxidation yield:
1) 7 Acetyl-CoA (= 84 ATP),
2) 7 NADH (= 21 ATP), and
3) 7 FADH2 (= 14 ATP).
The last revolution of β-oxidation yields one acetyl Co-A (= 12 ATP), producing a total of
131 ATP, (minus 2 ATP invested for FA activation), for a net of 129 ATP per molecule of palmitate.

palmitate is a 16 carbon fatty acid the oxidation of a molecule of palmitoyl CoA to CO2 and H2O produces 8 acetyl CoA, 7 NADH, and 7 FADH2, from which 131 ATP can be generated (electron transport chain); however, activation of the fatty acid requires 2 ATP. Thus, the net yield from palmitate is 129 ATP the no of acetyl CoA produced is no of C/2, the no of NADH and FADH2 is no of C - 1 because the last step only produces 1 NADH and FADH2 and 2 acetyl CoA
