Facilitated diffusion is the process of moving molecules across the membrane with the help of transport proteins to make the transportation of the molecules a lot easier and smoother.
Simple diffusion, however, does not have the assistance of transport proteins. Simple diffusion takes place when molecules move from a high concentration (of said molecule) to a low concentration.
The difference: Facilitated diffusion has the help of transport proteins while simple diffusion does not.

Most enzymes' optimum pH is neutral or close to neutral, like amylase found in saliva, which has an optimal pH = 6.8. Some enzymes prefer a more drastic pH, like pepsin, which can have an optimum pH of 1.7 to 2. Sometimes enzyme pH optima depends on where the enzyme is found.
