enzyme

3. the process of breaking down large molecules into smaller ones.
7. absorb energy from the surroundings to build the chemical bonds needed to form the products of the reaction
8. the shape of the active site is fixed and matches perfectly with the substrate
9. The active site has the ability to change shape to better fit the substrate
11. inhibit activity of enzyme, they reduce or stop the enzyme from functioning
12. organic cofactor required by enzyme to function properly

1. energy required to start any reaction
2. the final substances (molecules) formed at the end of a chemical reaction
4. the process of making large molecules from smaller ones
5. a substance that takes part in and undergoes change during a reaction.
6. the sum of all the chemical reactions occurring in that cell.
10. has a net release of energy because free energy is released from the reactants as the molecular bonds are broken.
