Across
- 3. The process of breaking down large molecules into smaller ones. As the bonds break, free energy is released.
- 7. A reaction that absorbs free energy from the surroundings.
- 8. The active site as having a set shape. The substrate molecules fit perfectly into active site, like a key in a lock.
- 9. A flexible active site that changes shape, or conforms, to the substrate as they bond together.
- 11. Inhibitors are molecules that inhibit the activity of enzymes.
- 12. Coenzymes, also known as organic cofactors, are non-protein molecules that bind to enzymes to help them function properly.
Down
- 1. The energy required to start any reaction
- 2. Products are the new substances formed at the end of the reaction.
- 4. The process of making large molecules from smaller ones. Free energy is absorbed from the surroundings to build new chemical bonds.
- 5. Starting materials (substrates) in a chemical reaction that undergo change.
- 6. The sum of all the chemical reactions occurring in a cell or a organism.
- 10. A reaction that has a net release of free energy.
