Q. Select the correct graph, which shows the effect of temperature on the velocity of a typical enzymatic reaction
A) [image:9_image23.emf]
B) [image:9_image24.emf]
C) [image:9_image25.emf]
D) [image:9_image26.emf]
Explanation
Enzymes generally function in a narrow range of temperature. Each enzyme shows its highest activity at a particular temperature, called the optimum value [image:9_image38.emf] Low temperature preserves the enzyme in a temporarily inactive state whereas high temperature destroys enzymatic activity because proteins are denatured by heat
