  15. Palmitic Acid Review

  16. Palmitic Acid -ATP Synthesis • Palmitic Acid is C-16 • Initiating Step - requires 1 ATP (text says 2) • Step 1 - FAD into e.t.c. = 2 ATP • Step 3 - NAD+ into e.t.c. = 3 ATP • Total ATP per turn of spiral = 5 ATP • Example with Palmitic Acid = 16 carbons = 8 acetyl groups • Number of turns of fatty acid spiral = 8-1 = 7 turns • ATP from fatty acid spiral = 7 turns and 5 per turn = 35 ATP. • NET ATP from Fatty Acid Spiral = 35 - 1 = 34 ATP

  17. Palmitic Acid (C-16) -ATP Synthesis • NET ATP - Fatty Acid Spiral = 35 - 1 = 34 ATP • Review ATP - Citric Acid Cycle start with Acetyl CoA • Step ATP produced • 7 visible ATP 1 • Step 4 (NAD+ to E.T.C.) 3 • Step 6 (NAD+ to E.T.C.)   3 • Step10 (NAD+ to E.T.C.)  3 • Step 8 (FAD to E.T.C.) 2 •  NET12 ATP per turn C.A.C. • 8 Acetyl CoA = 8 turns C.A.C. • 8 turns x 12 ATP/C.A.C. = 96 ATP • GRAND TOTAL130 ATP
