How does an enzyme recognize its substrate

WebMar 21, 2024 · An enzyme exhibits maximum activity over the narrow pH range in which a molecule exists in its properly charged form. The median value of this pH range is called the optimum pH of the enzyme (part (b) of Figure ). With the notable exception of gastric juice (the fluids secreted in the stomach), most body fluids have pH values between 6 and 8.
