At what ph would you expect amylase, the enzyme found in saliva, to work best?

Amylase in saliva work best at neutral pH or pH 7.  Many studies show that at this pH, the enzyme activity is the highest. When the enzyme reaches the stomach where it is an acidic environment amylase activity goes down or even stops. Then, as it enters the small intestine where the pH goes back to neutral level the amylase then resume to it's shape and works again.

This is what i found on google “when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and atp is converted to adenosine diphosphate (adp). likewise, energy is also released when a phosphate is removed from adp to form adenosine monophosphate (amp).” i hope this you .

It shows that the experiment is designed properly.
