Enzymes generally operate within a specific pH range, known as
"optimum pH." All enzymes need an average pH level in order to be able
to work, and some operate within a particular pH level appropriate to
their own working conditions. For instance, pepsin—which breaks down
proteins in the stomach—can work best only at a acidic pH of 2. Trypsin,
secreted by the pancreas and which plays a role in protein digestion,
works most efficiently at a pH of 8.5. But a powerfully acidic or alkaline
environment will damage most enzyme's structure. 55
Although enzymes demand highly sensitive working conditions, the
living body possesses the ideal properties for these molecules to function.
The fact that every one of the 2,000 types of enzymes in a living body can
work in a manner appropriate to its environment shows that both body
