Transcribed Image Text:

The enzyme phenolase catalyses the browning reaction of fruits and vegetables. This enzyme can be inhibited by sulphur dioxide (SO2). A student was tasked to determine what type of inhibitor SO2 was and they carried out the experiment in the presence and absence of the inhibitor and table D1 shows their raw data. D1a) Help the student using their raw data in Table D1 to determine what type of inhibitor SO2 is. Explain your answer in detail both in words and graphically such that the student can follow and understand. (5 Marks) Table D1: Raw data collected by the student [S] (mol/L) With SO2 Without inhibitor V(umol/min) = 2.2 X 104 M V(umol/min) 1 x 104 28.00 17.00 1.5 x 104 36.00 23.00 2 x 104 43.00 29.00 5 x 104 65.00 50.00 7.5 x 104 74.00 61.00 D1b) Calculate the value of Km in the presence and absence of SO2 (4 Marks) The enzyme phenolase catalyses the browning reaction of fruits and vegetables.
