Test the pH of substances like coffee and soap to see if they are acidic, basic, or neutral.
Enzymes are biological molecules used by living systems to catalyze specific reactions, and their activity depends on various factors such as temperature, pH, and concentration. Pepsin, a digestive enzyme found in gastric juice, helps digest food proteins into peptides in the stomach. Below is a graph illustrating the effect of pH on pepsin's reaction rate. Drag the red dots on the graph and pH scale in order to answer the following questions.
