What is the chemical handle attached to a fatty acid? - correct answer ✔✔Coa-S
How much energy is required to attach the handle to a fatty acid? - correct answer
✔✔2 ATP
What is the use of the handle attached to fatty acids? - correct answer
✔✔prevents the denaturation of the fatty acid and prevents the acid from acting
like a detergent in the cell.
How is a fatty acid transported into the mitochondria? - correct answer ✔✔Uses
antiport transportation through a translocase. Transports Acyl-carnitine into the
mitochondria and carnitine out.
Where on the molecule does fatty acid oxidation occur? - correct answer
✔✔Between the alpha and beta carbons
What bond is made during fatty acid oxidation? - correct answer ✔✔Trans double
bond
What is beta oxidation and where in the cell does it occur? - correct answer
✔✔Process which breaks down fatty acids by removing two carbons at a time;
oxidizes the beta-carbon of the fatty acid. It occurs in the mitochondrial matrix.
, What happens in the first reaction of beta-oxidation? - correct answer
✔✔Formation of trans double bond. Conversion of acyl-CoA to trans-delta^2-
enoyl-coA
What happens in the second reaction of beta-oxidation? - correct answer
✔✔Breaking of trans double bond, forms L-3-hydroxyacyl-CoA
What happens in the third reaction of beta-oxidation? - correct answer
✔✔Formation of the ketone; forms L-3-ketoacyl-CoA
What happens in the fourth reaction of beta-oxidation? - correct answer
✔✔Thiolase breaks down 3-ketoacyl-CoA to an acyl-coA and acetyl-coA
What happens to the acetyl coA produced by beta oxidation? - correct answer
✔✔It enters the citric acid cycle
What are the products of beta oxidation? - correct answer ✔✔1 FADH2, 1 NADH,
1 Acetyl CoA, 1 Acyl CoA shortened by 2 carbons
What is difficult about the oxidation of unsaturated fatty acids? - correct answer
✔✔Multiple double bonds in unanticipated locations can caused difficulty.
How does the cell help with beta oxidation of unsaturated fatty acids? - correct
answer ✔✔Utilizing isomerases to convert fatty acids into a metabolizable form
