.... Enzymes are biological catalysts. They control the rate of chemicla reactions which occur in living organisms (take place in cells) Without them rates would be so slow that life would not exist. the conditions they work best in are;
- pH of about 7.3 (saliva)
- Enzymes in the stomach need to be acidic
- Enzymes in the human body work best at around 37C
All chemical reactions are reversible. This means that the products will react to give the reactants that we started with.
Equilibrium- when a reversiable reaction occurs in a closed system. ( it occurs when reactions occur at exactly the same rate in both directions.)
