      Maximum rates attained () for an enzyme catalysed reaction at different temperature are given below. t/°C                          10     15     20     25     30     35     40    45     1.0    1.7    2.3    2.6    3.2    4.0    2.6    0.2 Comment about the enzyme activity.                                                                                                                                   [1]

    Answer:

      The observations show that maximum rate is attained at 35°C after which rate is decreased. Thus, optimum temperature for enzyme function is 35°C.                                              [1]
