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 the following questions answer with as much detail as possible. If a metabolic pathway is involved draw a name all molecular structures and name all enzymes. Indicate cell type and location within the cell as well as any transport mechanisms. Since the fatty acid pathways are serpentine, show one pass through the sequence and then you may simply state how many times a sequence is repeated until a new reaction is needed. If asked to synthesize a fatty acid,...
