Homework Answers
(A) Fatty acids degradation (beta oxidation) takes place inside the mitochondria.
(B) An electron carrier that is used during fatty acid synthesis is NADPH.
(C) Steps of fatty acid synthesis and the enzymes involved are-
Condensation of malonyl ACP with acetyl coA: beta-ketoacyl-ACP synthase
Reduction to beta-hydroxyacyl-ACP: beta-ketoacyl-ACP reductase
Dehydration to enoyl-ACP: 3-hydroxyacyl- ACP dehydrase
Reduction of enoyl-ACP: enoyl-ACP reductase.

Please help with questions #10 and #11. Fatty acid degradation is a slow process that occurs by cutting out 2 carbon units at a time. Question 8: (3 points) what are all the reagents other than the fatty acid needed for this process? All the reagents needed in beta-oxidation of fatty acid break down are – acyl coA dehydrogenase to form enoyl coA, enoyl coA hydratase to form 3-hydroxy acyl coA, hydroxy acyl-coA dehydrogenase to form beat-ketoacyl coA, and thiolase...

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...
