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,...
