Explain how living organisms may use the differences between fatty acid synthesis and degradative pathways to regulate these pathways. (6) Use the differences between fatty acid oxidation and synthesis to show that these two processes can be regulated using location and intermediates involved in their reactions. (4) Using the regulation of fatty acid synthesis as an example, explain the differences between short and long term regulation in synthesis pathways. (6).
