Enzymes, they are proteins that function as a biological catalyst that speed up rate of chemical reactions without themselves being chemically charged at end of reaction.
characteristics
- Enzymes remain chemically unchanged after reaction
- Enzymes are required in minute amounts
- Enzymes are highly specific
- speed up chemical reactions
5, Enzymes are affected by temperature and PH
lock and key hypothesis
- This forms an enzyme-substrate complex.
- Substrate starch forms the product maltose and maltose leaves the active site.
- Only starch can bind complementarily to the active site of amylase.
- The enzyme remains unchanged and can be reused again.
- Enzyme amylase acts as the lock, substrate starch acts as key.
