A) citrate B) succinyl CoA C) oxaloacetate D) alpha-ketoglutarate E) None of the answers is correct. What pathway degrades an acyl-CoA into acetyl CoA? A) acyl transferase cycle B) chylomicron cycle C) glyoxylate cycle D) camitine cycle E) beta oxidation Which lipoprotein particle transports triacylglycerols from the intestine? A) chylomicron B) very low density lipoprotein C) intermediate density lipoprotein D) low density lipoprotein E) high density lipoprotein Which of the following has the elements of the electron transport chain in the CORRECT order? A) NADH-Q reductase; ubiquinone; cytochrome c; Q-cytochrome c oxidoreductase; cytochrome c oxidase B) cytochrome c oxidase; cytochrome c; Q- cytochrome c oxidoreductase; ubiquinone; NADH-Q reductase C) NADH-Q reductase; ubiquinone; Q- cytochrome c oxidoreductase; cytochrome c; cytochrome c oxidase D) cytochrome c; Q- cytochrome c oxidoreductase; NADH-Q reductase; cytochrome c oxidase; ubiquinone E) NADH-Q reductase; cytochrome c; Q-cytochrome c oxidoreductase; cytochrome c oxidase; ubiquinone The coenzyme(s) involved in the degradation of saturated fatty acyl CoA is/are: A) FAD. B) NAD^+ C) TPP. D) FAD and NAD^+. E) All the answers are correct.Explanation / Answer
25) B oxidation of odd-numbered fatty acids produces acetyl-CoA and propionyl-CoA
Fatty acids with an odd number of carbons chain, release 1 unit of Acetyl CoA and 1 unit of Propionyl CoA. And two Acetyl CoA units released when a fatty acid with an even number of carbons is beta-oxidized.
Answer is propionyl-CoA
26) Answer is C
The levels of oxaloacetate determine whether acetylCoA, made from fatty acids,can enter the citric acid cycle.
27) Answer is E
B oxidation degrades an acyl-CoA into acetylCoA
oxidation undergoes oxidative removal of successive two-carbon units in the form of acetyl-CoA
28) Answer is A
chylomicron transports triacylglycerols from the intestine.
Chylomicrons are lipoprotein particles that consist of triglycerides , phospholipids , cholesterol , and proteins.
Transports dietary lipids from the intestines to other parts of the body.
