Across
  1. 5. General mechanism of enzyme activity regulation in which a molecule other than the enzyme's substrate is able to bind the active site and prevent the substrate itself from binding, thus inhibiting the overall rate of reaction for the enzyme
  2. 7. Type of chemical reaction that results in products with less chemical potential energy than the reactants, plus the release of free energy
  3. 8. Ability to do work
  4. 9. Molecule on which the enzyme acts
  5. 10. Molecule that catalyzes a biochemical reaction
  6. 11. Type of energy that refers to the potential to do work
  7. 12. Metabolic pathway in which complex molecules are broken down into simpler ones, yielding energy as an addiction product of the reaction
  8. 13. States that energy cannot be created nor destroyed
  9. 17. Amount of initial energy necessary for reactions to occur
  10. 20. Type of chemical reaction that results in products that store more chemical potential energy than the reactants
  11. 21. The science of the relationships between heat, energy, and work
  12. 22. Type of energy associated with objects in motion
  13. 23. General mechanism of enzyme activity regulation in which regulatory molecules bind to a site other than the active site and prevents the active site from binding the substrate; thus the inhibitor molecule does not compete with the substrate for the active site. Allosteric inhibition is an example of this
Down
  1. 1. States that all energy transfer reactions are not entirely efficient, and some energy is always lost in an unusable form, typically as heat
  2. 2. System in living things that detect changes in physiological characteristics in living things, that illicit a response to stop or reverse that change
  3. 3. Specific region on the enzyme where the substrate binds
  4. 4. Concept of energy flow through living systems
  5. 6. System in living things that detects changes in physiological characteristics in living things, illicit a response to further or amplify that change
  6. 14. All of the chemical reactions that take place inside cells, including those that use energy and those that release energy
  7. 15. Mechanism of enzyme activity regulation in which the product of a reaction or the final product of a series of sequential reactions inhibits an enzyme for an earlier step in the reaction series
  8. 16. Mechanism for inhibiting enzyme action in which a regulatory molecule binds to a second site (not the active site) and initiates a conformation change in the active site, preventing binding with the substrate
  9. 18. Metabolic pathway that requires a net energy input to synthesize complex molecules from simpler ones
  10. 19. Energy transferred from one system to another that is not work
