To calculate the energy generated by the oxidation of a

To calculate the energy generated by the oxidation of a fatty acid Fatty acids yield more than twice as much energy per gram as carbohydrates The image below shows the B oxidation pathway a series of four reactions that oxidizes fatty acyl SCoA to acetyl SCOA Note that the fatty acid is converted to fatty acyl SCOA energy requiring process before it enters the B oxidation pathway The hydrocarbon tail of the fatty acid is represented by CH atoms and the R group in acyl SCOA Y Part A AEO S Step 4 A carbon carbon bond is broken to yield acetyl SCOA and a chain shortened fatty acid BHE 2 Step 3 The alcohol group is oxidized to a ketone The coenzyme NAD is used H SCOA 4 iza i R CH CH C CH C SCOA R CH CH R CH CH C SCOA CH3 C SCOA Calculate the number of molecules of acetyl SCoA derived from a saturated fatty acid with 22 carbon atoms Express your answer as an integer View Available Hint s molecule s H H R CH CH CH CH C SCOA 4 NADH H NAD 11 Further oxidation repetition of Steps 1 4 1 Energy is generated from the electrons of FADH and NADH that enter the electron transport chain and from the passage of acetyl SCOA through the citric acid cycle FAD H R CH CH OH R CH CH CH CH C SCOA 2 41 0 FADH Step 1 A double bond is introduced by enzyme catalyzed removal of two hydrogens from carbons 2 and 3 The coenzyme FAD is needed for this step C SCOA H Step 2 Water adds to the double bond to yield an alcohol
