to the rate of an enzyme-catalyzed reaction if the concentration of substrate changed. We hypothesized that if the concentration increased‚ then the reaction rate would also increase. To test our question‚ we varied a combination of substrate and buffer‚ totaling 6mL‚ with a constant amount of 2 drops of catalyst. The enzyme catalyst‚ peroxidase‚ increased the rate of the reaction. The results of our experiment can be found by comparing the reaction rates for each trial. These rates are actually

a work stress that produces marital conflict or a parent that does not have child care and therefore have higher rates of absenteeism. These are examples of the conflict that can arise when trying to balance both work and family. There are some buffers however to help eliminate or at least reduce the conflict that can arise or the spillover of one piece of a person ’s life into the other. Some individuals do not make their home number available to their workplace in order to reduce the extent to

Calibration should be performed with at least two standard buffer solutions that span the range of pH values to be measured. For general purposes buffers at pH 4 and pH 10 are acceptable. The pH meter has one control (calibrate)
