ENZYMES are proteins that SPEED UP CHEMICAL REACTIONS
Instructions for making enzymes are found in the cell's genes.
Enzymes are very specific:
- Chemical reactions usually involve things either being split apart or joined together.
- A substrate is a molecule that is changed in a reaction.
- Every enzyme molecule has an active site - the part where a substrate joins on to the enzyme.
- Enzymes are really picky - they usually speed up one rection. This is because for an enzyme to work a substrate has to be the correct…
