5. ( pts) Draw the complete B-oxidation pathway of the following short chain fatty Acyl-CoA. Show the structures of all reactants and products, as well as the names of the enzymes. You do not need to draw the structures of ATP, NADT, COA, etc., but do show them as reactants or products in the appropriate places. You do not need to show the mechanisms of the enzymes. (b) (3 pts) How many ATPs would be generated by the complete oxidation...

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...

Need help with both questions, thank you!
Question 11 The final product of fatty acid oxidation of an odd-numbered fatty acid chain is propionyl COA. What is it converted to? alanine succinyl COA O glutamate ketone bodies acetyl COA Question 12 Fatty acid synthesis is reductive biosynthesis. What molecule reduces the carbons during fatty acid synthesis? NADPH O heme FADH2 O NADH acetyl COA

True or false? True False The function of the enzyme acyl CoA synthetase is the ATP-dependent coupling of fatty acids to CoA. True False Unsaturated fatty acids contain zero alkene bonds. True False The brain uses ketones instead of glucose for ATP production during long-term fasting. True False A biotin-deficient diet may lead to an increase of cytosolic acetyl CoA. True False Untreated, chronic ketone body production will raise blood pH levels. True False The availability of the metabolite malate determines whether acetyl CoA, made from...

All of the following statements about beta-oxidation are true EXCEPT * Select only ONE answer choice. The pathway helps to generate energy and acetyl CoA from fatty acyl CoA -The pathway produces NADH and FADH2 as products -The pathway is found in all tissues that contain mitochondria -The pathway feeds fatty acids into Glycolysis as acetyl-CoA -The pathway is rate limited by oxygen availability
