1. Is the enzyme digested and absorbed? (vd: Is amylase digested by protease?)
2. How does the body know how much enzyme to produce to match the amount of substrate it needs to metabolize?
3. What happens to the excess secreted enzymes?
4. What does the IU in enzyme supplements represent?
Thank you very much.
Answer
This is just barely related to nutrition. Try to ask on more biology or biochemistry related subs. Or you can try your luck on r/explainlikeimfive which tends to be pretty helpful since there’s a large and relatively friendly community.
