    Answer: check explanation

    Explanation:

    Note: The answer will vary depending on the amount of ATPS per NADH is been used.

    Beta-oxidation is a process by which fatty acid molecules are broken down in prokaryotes' cystol and in the mitochondria in eukaryotes with the production of acetyl-CoA.

    In 7 cycles of mitochondrial beta oxidation of palmitic acid, oxidation of palmitic acid yields; 7 NADH + 7 FADH2 + 8 acetyl-CoA.

    The acetyl-CoA will then yield 3 NADH + 1 FADH2 + 1 GTP during Krebs cycle.

    Palmitic acid contains 16 carbon. Therefore, 16/2 = 8.

    Hence, 8 acetyl coA * 10 ATP/acetyl CoA.

    = 80 ATP.

    Therefore, (7 cycles * 4 ATP/cycle.

    = 28 ATP.

    So, (80 + 28) ATP - 2ATP (for FA activation.

    = 106 net ATP yield.
