Design an experiment in which I will test the effect of an acidic fluid on enzymatic activity. I need to an outline of how an acidic fluid will modify the outcome of an enzymatic reaction. I will need to identify the enzyme, the substrate, the acidic fluid used as treatment, the control treatment and the method of measuring enzyme activity, as well as explain my experimental protocol. I must also thoroughly explain how the acidic fluid impacted enzyme activity based on the results from my experiment as well as knowledge of enzymes and pH.
