Across
- 3. pathways in which complex molecules are broken down into simpler ones
- 7. small organic molecule, such as a vitamin or its derivative, which is required to enhance the activity of an enzyme
- 8. molecule on which the enzyme acts
- 10. all the chemical reactions take place inside cells, including anabolism and catabolism
- 11. the usable energy, or energy that is available to do work
- 13. type of energy associated with objects or particles in motion
- 14. energy necessary for reactions to occur
- 16. inorganic ion, such as iron and magnesium ions, required for optimal regulation of enzyme activity
- 17. type of inhibition in which the inhibitor competes with the substrate molecule by binding to the active site of the enzyme
- 18. dynamic fit between the enzyme and its substrate, in which both components modify their structures to allow for ideal binding
- 20. effect of a product of a reaction sequence to decrease its further production by inhibiting the activity of the first enzyme in the pathway that produces it
Down
- 1. pathways that require an input of energy to synthesize complex molecules from simpler ones
- 2. specific region of the enzyme to which the substrate binds
- 4. type of energy that has the potential to do work; stored energy
- 5. describes chemical reactions that require energy input
- 6. study of energy and energy transfer involving physical matter
- 9. inhibition by a binding event at a site different from the active site, which induces a conformational change and reduces the affinity of the enzyme for its substrate
- 12. describes chemical reactions that release free energy
- 15. adenosine triphosphate, the cell's energy currency
- 19. measure of randomness or disorder within a system
