ecom nm oblem-902729 hapter 24 Energy from Fatty Acid Oxidation previous i 16of 16 rehan Ioassgment To calculate the energy gonerated by the oxidation of a fatty ackd Fatty acids yield more than twice as much energy per gram as carbohydrates. The image below shows the B oxidation pathway, a series of lour reactions that oxidzes falty acyl SCoA to acetyl-SCoA. Note that the fatty acid is converted to fatty acyl SCoA, an enorgy-requinng process, betore it enters the B-oxidation pathway. The hydrocarbon tail of the fatty acid is represented by CH2 atoms and the R group in acyl SCOA Step 1. A double bond is introduced by enzyme catalyzed removal of two hydrogems from carbons 2 and 3. The coenayme FAD is needed for this step. R-CH2CH2-CH-CH-C SCOA FAD Step 4. A carbon-carbon bond is broken to yield acetyl-SCoA and a chain- H- shortened fatty acid Further oxidation (repetition of Steps 1-4) H,0 Step 2. Water adds to the double bond to yield an alcohol. OH Step 3. The alcohol group NADH/H* is oxidized to a ketone. The coenzyme NAD+ is used. NADR-CHCH2 CH-CH2-C-SCoA O Type here to search

Explanation / Answer

Answer:

C10 + AcetylCoA
C8 + AcetylCoA
C6 + AcetylCoA
C4 + AcetylCoA
C2 + AcetylCoA
AcetylCoA

so in this case the total AcetylCoA would be 6 .
