The pH level found in the stomach is between 1 and 3. The hypothesis of this experiment is that pepsin enzyme works best in the conditions where the pH level is closer to the one found in the stomach, which means that the optimum pH level for the pepsin enzyme activity would be between 1 and 3. Anything out of that range will inhibits the enzyme activity, meaning that less acidic or more basic environments will not allow the reaction to occur.
