Evaluate the hypothesis presented above and formulate the predictions based on the hypothesis in theLab Report below.2. Label four tubes for serial dilution of the substrate, S1:10, S1:100, S1:1000, S1:10000), and fill the tubeswith 9 ml of distilled water (“S” for “substrate”).3. Following the serial dilution procedure outlined in Figure 3.2, transfer 1 ml of the stock solution ofcatechol into tube S1:10 and mix thoroughly by shaking the tube.

This is a ten-fold dilution of thesubstrate.4. Transfer 1 ml of the ten-fold dilution of catechol from tube S1:10 to tube S1:100 and mix thoroughly byshaking the tube. This is a hundred-fold dilution of the substrate.5. Transfer 1 ml of the hundred-fold dilution of catechol from tube S1:100 to tube S1:1000 and mixthoroughly by shaking the tube. This is a thousand-fold dilution of the enzyme.6. Transfer 1 ml of the thousand-fold dilution of catechol from tube S1:1000 to tube S1:10000 and mixthoroughly by shaking the tube. This is a ten thousand-fold dilution of the enzyme.7. Label test tubes C1, C2, C3, C4, C5, and C6 and place 3 ml of the enzyme (catecholase) in each tube.8. Add 3 ml of catechol stock solution to tube C1 (Table 3.5).9. Add the diluted substrate to the tubes C2C5 from the tubes S1:10, S1:100, S1:1000, and S1:10000,respectively, as shown in Table 3.5.10.
