Sr. #	Questions	Answers Choice
1	How does a non competitive inhibitor decrease the rae ofn enzyme catalysed reaction.	By chaing the free energy change of the reaction By acting as a coenzyme for the reaction By changing the shape of the enxyme By binding the active site of the enxyme
2	If an enzyme solutionis saturated with substrate, the most effective way to obtain an even faster yield of products would be.	Add more of the enxymes Add more substrate Add an allosteric inhibitor Add a non competitive inhibitor
3	Enxyme B requires Zn+2 to catalyse the conversion of substrate X. The zinc is best identified as a .	Product Substrate Activator Coenzyme
4	Which of the following statemetns about enzymes is correct.	They increasse the activation energy of a reaction They are consumed during the reaction They are specific in terms of the reactions they catalyse They always wor optimally at high temperatures.
