Review Questions:
- Because the action of lipase produces fatty acids which will
change the pH of the solution.
- This would probably work best in the stomach where the pH tends to
be low.
- Bile breaks up the lipid molecules to make it easier for the
lipase to attack them and break them down.
- Because BAPNA is clear until pepsin breaks it down, at which point
it has a detectable color change.
- All of the enzymes are present in the human body, so they should
have an optimal temperature at normal human body temperature.
