Activity-Based Estimates. An activity can have costs from multiple vendors in addition to internal costs for labor and materials. Detailed estimates from all sources can be reorganized so those costs that are associated with a particular activity can be grouped by adding the activity code to the detailed estimate, as shown in Figure 9.4.

The correct pH can vary greatly. Pepsin is an example of an enzyme that works best when pH is about 1.5. Heating an enzyme above a certain temperature will destroy the enzyme permanently. It will be broken down by protease and the chemicals will be used again. Some chemicals can help an enzyme do its job even better. These are called activators ...

Effects of Temperature, pH, and Gelatin on BromelainIntroduction Bromelain is an organic catalyst that speeds up the rate of chemical reactions. Bromelain is used in this experiment to catalyze the break down of proteins and is called a proteolytic enzyme.
The third section was the effect of pH on the enzyme activity. The optimum pH of the reaction was 5.5. This pH gave the highest reading of absorbance which means that the rate of hydrolysis was at its highest. Finally the last section of the experiment was the effect of competitive inhibitor on the rate of reaction.

γ is the activity coefficient of an ion of charge ±z and size α (in picometers, pm) in an aqueous solution of ionic strength μ. The equation works fairly well for μ ≤ 0.1 M. To find activity coefficients for ionic strengths above 0.1 M (up to molalities of 2–6 mol/kg for many salts), more complicated Pitzer equations are usually used.
