Homework Answers
Difference between fatty acid synthesis and beta oxidation.
1. Fatty acid synthesis takes place in cytoplasam of prokaryotes, whereas beta oxidation takes place in mitochondrial matrix of eukaroytes.
2. The enzymes of fatty acid synthesis are joined in a single polypeptide chain called as fatty acid synthase whereas in beta oxidation, the degardative enzymes are not associated.
3. Products formed/ Intermediates formed in fatty acid synthesis are linked to the sulfhydryl group of ACP (Acyl Carrier Protein) through covalent bond where as in beta oxidation the intermediates are attached to sulfhydryl group of Coenzyme A.
4. The reduction in fatty acid synthesis is NADPH whereas the oxidants in beta oxidation (fatty acid degradation) are FAD and NAD+.
5. The energy requirement in fatty acid synthesis is 49 ATP equivalents whereas in beta oxidation 33 ATP equivalents are released.
The similarities between beta oxidation and fatty acid synthesis are:
1. Oxidation of FAD
2. The hydration
3. Oxidation of NAD+

In metabolic pathways, there are two redox reactions that occur repeatedly: 1. The reduction of a carbonyl- keto or aldehyde- to an alcohol (oxidation of an alcohol to a carbonyl). An example is the interconversion of pyruvate and lactate. OH E°-0.19 V pyruvate lactate Question 1: a) b) c) What is the redox potential for the reduction of pyruvate by NADH? What is the ΔGom At equilibrium will more pyruvate be present or more lactate?

For each two carbon fragment that is removed in beta oxidation, 1 FADH2 and 1 NADH + H+ are produced. Each FADH2 can produce two ATP, and each NADH can produce 3 ATP. Each two carbon fragment enters the Kreb's cycle. If you were to completely metabolize a 14 carbon fatty acid by beta oxidation, you would get 6 FADH2 and 6 NADH + 6H+ from beta oxidation, and you would have 7 acetyl CoA molecules that would enter the...
