In order to move from one place to another in the cell fatty acids need to associate with lipid chaperones. Why are these chaperones required, and what is the name of this group of proteins that are responsible for this trafficking of fatty acids within the cell? What is the main distinguishing feature of these proteins that makes it possible for fatty acids to move within the cell?

An enzyme with a Vmax of 100 umol/minute and a Km of 10 uM was reacted with a irreversible active site specific inhibitor. After reaction with the inhibitor, the enzyme was assayed using a 2 mM concentration of substrate, and it gave a reaction rate of 20 umol/min. What percentage of the enzyme did the inhibitor inactivate?
