All this suggests that having more AMY1 copies is beneficial for mammals that consume a lot of starch, but oddly, scientists still haven’t determined exactly how multiple copies of a salivary amylase ...

At the optimum temperature the amylase will break down starch very quickly. At low temperatures the amylase will break starch down slowly due to reduced kinetic energy.

The amylase will break down the starch. A series of test tubes containing a mixture of starch and amylase is set up at different pHs.
