Muscle cells use a lot of energy and also have higher amounts of the ATP synthase enzyme than many ouier cem types. General mechanism of enzyme regulation: /1 b) Prostaglandins are messenger molecules involved in the inflammatory response, as well as th perception of pain. They are synthesized from polyunsaturated fatty acid substrates by an enzyn called cyclo-oxygenase. "Ibuprofen" is the active ingredient in a variety of anti-inflammatory medications such as Motrin® and Advil®. It reduces pain and swelling by binding to a hydrophobic channel in the active site of cyclo-oxygenase, blocking the polyunsaturated fatty acids from binding to the enzyme, and therefore stopping production of prostaglandins.
