A 12 carbon fatty acid generates 6 molecules of acetyl CoA. How many molecules of ATP can be generated from this fatty acid if you consider the production all the way through the electron transport chain?

Solutions

Expert Solution

6 acetyl CoA can be produced from the 12 carbon fatty acid.

acetyl CoA enters TCA cycle, via each TCA cycle 3 NADH, 1 FADH2, and 1 ATP.

total number of NADH produced via TCA cycle of 6 acetyl CoA via the TCA cycle= 63=18

total number of FADH2 produced via TCA cycle of 6 acetyl CoA via the TCA cycle= 61=6

total number of ATP produced via TCA cycle of 6 acetyl CoA via the TCA cycle= 61=6

total number of NADH produced from the fatty acid= 18

total number of FADH2 produced=6

total number of ATP can be produced from NADH= number of NADH3=183=54

total number of ATP can be produced from FADH2= number of FADH22=62=12

so total number of ATP can be produced from electron transport chain= number of ATP produced from TCA cycle + number of ATP produced via electron transport chain= 6+54+12= 72

total number of ATP produced from the fatty acid=72

1. Myristoyl-CoA is a saturated fatty acid with 14 carbons attached to coenzyme A. How many molecules of ATP would be generated from the complete oxidation of a single molecule of myristoyl-CoA? Important notes: Recall that the investment of 2 ATP is required to generate Myristoyl-CoA from myristate. Do not include these 2 ATP in your calculations of ATP yield. Assume that each molecule of NADH corresponds to 2.5 ATP synthesized, and each molecule of FADH2 leads to 1.5 ATP...
