how many of the following molecules would be required to build a 12-carbon fatty acid:
__ acetyl CoA, ____ ATP, ___ bicarbonate, and ____ NADPH
How many of the following molecules would be required to build a 12-carbon fatty acid:
Answer: The Lauric acid is a 12 carbon fatty acid and to synthesize lauric acid 6 acetyl CoA units, 5 molecule of ATP and 10 molecules of NADPH and 5 bicarbonate are required.
Explanation behind the 5 bicarbonate ion is that out of 6 acetyl CoA unit only one unit is used to form the two carbon atom farthest from the acid end whereas the other 5 units of acetyl CoA is being converted into Malonyl CoA., which is the product of carboxylation reaction and the first step of fatty acid synthesis. The Malonyl CoA is formed from the bicarbonate and acetyl CoA.

A fatty acid composed of 20 carbon atoms undergoes β‑oxidation. How many acetyl CoA, FADH2, and NADH does β‑oxidation of this fatty acid generate? (answer is 10 acetyl CoA, 9 FADH2, 9 NADH) Calculate the net ATP generated by the β‑oxidation of the 20‑carbon fatty acid. Assume that each FADH2 generates 1.5 ATP and each NADH generates 2.5 ATP. number of ATP molecules: ??????

Fatty Acid Metabolism. The reactions of the fatty acid spiral are shown below. Use the description on the left side of the page to classify the reactions and fill in the boxes on the right side of the page Activation Step. The activation of the fatty acid begins by the addition of CoA which will carry the fatty acid from the cytosol into the mitochondria. The product, which is a fatty acid with a CoA attached, is known as a...
