If anything under 7 is acidic and rennet , in its first stage, us 5.8. Then the optimum pH for rennet is acidic
slightly acidic, remember most organisms have an optimum pH of 6.6 or so.
Pepsin is therefore acidic since the pH in the stomach is 2
I believe it's 7.3, the pH of human blood, as most enzymatic reactions occur there. However, there are special enzymes, such as the ones which are in the stomach, which work best at around a pH of 2.
The optimum pH for tyrosinase activity is typically around pH 6.5 to 7.5. This enzyme functions best in slightly acidic to neutral conditions. Extremes in pH levels can denature the enzyme and reduce its activity.
Adding base will increase pH-level
The optimum pH of salivary amylase is 6.8 (slightly acidic).
a pH scale.
The optimum pH for stomach protease, specifically pepsin, is around 1.5 to 2. It functions best in the highly acidic environment of the stomach, which helps to break down proteins efficiently for digestion.
The optimum PH of pepsin ranges between 1.0 and 4.0. Pepsin exhibits about 90 percent of the maximum activity and about 35% of the maximum activity.
When adding a strong acid to an acidic solution pH decreases. Adding a strong base to an acidic solution the pH increases.
pH value more than 7 is basic and lesser is acidic
acidic below 7 is acidic, above 7 is a base, and 7 is neutral.
