Enzymes

2. The chemical to which an enzyme binds are the enzyme's substrates
4. absorbs free energy from the surroundings.
7. Organic molecules such as vitamins and NAD+
9. hinder the activity of enzymes. That is, they reduce or stop the enzyme from functioning.
10. the end substances created at the conclusion of an enzyme-catalyzed chemical reaction
11. the process of making large molecules from smaller ones.

1. The energy required to start any reaction
3. a net release of free energy.
5. The model of enzyme activity describes a flexible active site that changes shape, or conforms, to the substrate as they bond together.
6. The sum of all the chemical reactions occurring in that cell.
7. the process of breaking down large molecules into smaller ones.
8. The model describes the active site as having a set shape. The substrate molecules fit perfectly into active site, like a key in a lock. Once in the active site, the chemical reaction can take place.
