Figure 6. Percent Transmittance of an amylase amylum solution in 3 minute intervals with changing pH

Starch Hydrolysis Discussion

This experiment was conducted to demo if changing the pH in an environment will alter the rate of the reaction between amylum and amylase. The pH of the amylum amylase solution was the independent variable, and the sum of light being transmitted through the solution after adding I was the dependent variable. The tabular arraies and figures determine the reaction rate by plotting the per centum of visible radiation transmitted versus clip measured to acquire an equation. The void hypothesis of changing the pH of the enzyme solution will non impact the reaction between amylum and amylase is in wrong harmonizing to tabular arraies 1 -5. The changing pH groups in a solution had different rates harmonizing to table 6. The consequences showed that the first pH to make 100 % was the pH of 6.0. Harmonizing to table 1 it took 51 proceedingss for the pH 6.0 solution to make 100 % transmission. The solution of pH 7.0 took 57 proceedingss to make 100 % transmission harmonizing to table 3. Merely 6 proceedingss from the pH of 6.0. Harmonizing to table 2 the 2nd pH of 7.0 ( control ) showed 100 % transmission at 66 proceedingss. The solution of pH 8.0 took 90 proceedingss to make 100 % transmission harmonizing to table 4, most probably because it is more basic. The pH of 9.0 was either a dark naval forces or dark orange for most of the experiment. The solution of pH of 9.0 did non make 100 % transmission. Harmonizing to table 5 the pH of 9.0 solution took a sum of 96 proceedingss to make a transmission of merely 62 % .The pH of 9.0 solution ran out before it reached 100 % . Refering to the informations in figure 5 it took about 40 proceedingss earlier much visible radiation was transmitted for pH of 9.0. The solution of pH 9.0 had the slowest rate of the 5 changing pH solutions ; the rate was 0.646 harmonizing to table 6. The pH with the fastest rate was pH 6.0 with a rate of 1.961.

Mentioning the information from figure 6 the pH 0f 9.0 had the lowest per centum transmission. Not excessively far behind was the pH of 8.0. The solutions with a pH of 6.0, 7.0 and the control group were near in per centum transmission.

Decision

In decision the hypothesis for the amylum, amylase experiment was right. Yes changing the pH of the enzyme solution will impact the rate of the reaction between amylum and amylase. The 5 different pH groups, pH 6.0,7.0, 7.0 ( control ) 8.0 and 9.0 used in this experiment all had different reaction rates and different times when the per centum transmission reached 100 % .It was discovered that the information dropped a few times. This could hold been because the standardization was non completed plenty. This besides could hold been because cuvettes may hold had finger Markss and non decently wiped off. Another inquiry to be proposed would be, does changing the pH in different solutions change the reaction rate

between amylum and amylase?
