I need some help on this question. I know that three are correct, but the options I try are not working. Please help.

The beta oxidation pathway degrades activated fatty acids (acyl-CoA) to acetyl-CoA, which then enters the citric acid cycle. Additional enzymes are required to oxidize unsaturated, odd-chain, long-chain, and branched fatty acids. Which of the following statements are true? Trans double bonds in unsaturated fatty acids are not recognized by beta oxidation enzymes. A 14-carbon monounsaturated fatty acid with cis configuration yields more ATP than a 14-carbon saturated fatty acid. Enoyl-CoA isomerase, an enzyme that converts cis double bonds to trans double bonds in fatty acid metabolism, bypasses a step that reduces Q, resulting in a higher ATP yield. Even-chain saturated fatty acids are oxidized to acetyl-CoA in the beta oxidation pathway. Complete catabolism of the three-carbon remnant of a 15-carbon fatty acid requires some citric acid cycle enzymes. The final round of beta oxidation for a 13-carbon saturated fatty acid yields acetyl-CoA and propionyl-CoA, a three-carbon fragment.

Explanation / Answer

the correct answers are statements 4,5, and 6
