The buffer is a substance that is resistant to the change in the body’s pH level. Basically the buffers can make an acid or base less potent and try and neutralize it so the body is

Finding the Optimal pH of the Enzyme Peroxidase with the Aid of a Spectrophotometer ABSTRACT The peroxidase enzyme was partially purified‚ and the enzyme activity was calculated with the use of a spectrophotometer‚ demonstrating the effect of pH on peroxidase activity. The objective of this exercise was to determine the ideal pH for peroxidase activity. The data concluded that the optimum pH for peroxidase activity is 5‚ and the “standardized” enzyme volume is 2.8mL

Experiment 1 : Design and preparation of buffers effective at different pHs Abstract The body uses natural buffers to maintain the many different pH environments in our body. This is important for optimum activity of our enzymes. When doing experiments in vitro using these enzymes it is important to mimic intracellular conditions using artificial buffer systems in order to obtain accurate results. In this experiment the buffering properties of three artificial buffer systems containing acetic
