[1] Sample Calculation: Show your enzyme reaction rate calculation for Trial 1.

5.17ppt/20.0 = .2585

[2] Convert enzyme concentrations of 2.5%, 5.0%, and 10% to ppt units.

[3] For Procedure I/Table I, identify:

Independent variable:

Dependent variable:

Control variables:

[4] Draw a graph of the independent variable on the x-axis (abscissa) and the dependent variable on the y-axis (ordinate). Label the axis titles and units.

[5] Sample Calculation: Show your enzyme reaction rate calculation for Trial 1.

[6] Using the data you reported in the Table above, describe the effect of temperature on the reaction rate.

[7] Sample Calculation: Show your enzyme reaction rate calculation for Trial 1.

[8] Choose either a bar graph or a line graph format and plot the data for Procedures II and III. Plot the data for each Procedure on a separate plot.

[9] Compare the plot of the data for Procedures I, II, and III. Describe the differences among the three plots.

[10] What conclusions can draw about the effects of concentration, temperature and pH on the reaction rate after comparing the plots from the three different Procedures?

[11] Choose one of the factors that impacts reaction rate (concentration, temperature, or pH) and, in your own words, provide a plausible biological explanation for your experimental results for that factor.
