Energy and Enzymes
Across
- 4. ideal conditions for a specific enzyme to function
- 8. term that describes the slowing down of an enzyme-catalyzed reaction as substrate concentration increases
- 9. typically a mineral that reversibly interacts with and is essential for enzyme function
- 13. term for the items that go into a chemical reaction
- 15. includes factors that affect the rate of an enzyme-catalyzed reaction such as temperature, pH, and substrate concentration
- 19. state where substrate bonds are partially formed or broken down, involving changes in the shape of the enzyme
- 20. term that describes the specificity of the shape and charge of the substrate binding domain for a specific substrate
- 22. a reaction where the reactants and products have the same free energy (deltaG=0)
- 25. site in an enzyme where the substrate(s) binds
- 26. a reaction that requires heat to occur
- 27. molecules that enzymes work on
- 29. primary sequence of amino acids
- 31. degree of disorder in a system
Down
- 1. disruption in the genetic code that may ultimately affect enzyme structure and function
- 2. type of regulation where the regulatory molecule binds outside of the active site causing shape changes that can activate or inhibit the enzyme
- 3. type of inhibition where a product of a metabolic pathway binds to, and inhibits, an enzyme that functions early in the pathway
- 5. type of inhibition where the inhibitor competes with the substrate(s) for an enzyme’s binding site
- 6. step of enzyme catalysis where substrates bind the enzyme
- 7. component that facilitates a reaction but is unchanged by the reaction
- 10. type of energy required to reach the transition state
- 11. stored energy
- 12. a reaction that is not energetically favorable (deltaG>0)
- 14. a reaction where the reactants have higher free energy than the products
- 16. a reaction that releases heat
- 17. step of enzyme catalysis where products are discharged from the enzyme
- 18. non-amino groups that covalently attach to enzymes, altering their function
- 21. all of the things that are produced by a reaction
- 23. term for free energy that takes into account entropy, enthalpy and temperature
- 24. a favorable, spontaneous reaction (deltaG<0)
- 26. internal energy of a system including heat, pressure and volume
- 28. molecules that shuttle electrons and reversibly interact with an enzyme to enhance its function; often vitamins or their derivatives
- 30. typically a protein that facilitates a chemical reaction by bringing substrates together
