Across
- 4. The principle stating that every energy transfer or transformation increases the entropy of the universe.
- 9. A substance that reduces the activity of an enzyme by entering the active site in place of the substrate, whose structure it mimics.
- 12. An organic molecule serving as a cofactor
- 13. The principle of conservation of energy: Energy can be transferred and transformed, but it cannot be created or destroyed.
- 14. The energy associated with the relative motion of objects.
Down
- 1. The totality of an organism's chemical reactions, consisting of catabolic and anabolic pathways, which manage the material and energy resources of the organism.
- 2. The portion of a biological system's energy that can perform work when temperature and pressure are uniform throughout the system.
- 3. A kind of allosteric regulation whereby a shape change in one subunit of a protein caused by substrate binding is transmitted to all the other subunits
- 5. A series of chemical reactions that either builds a complex molecule or breaks down a complex molecule into simpler molecules
- 6. A molecule (often a reactant) with a phosphate group covalently bound to it, making it more reactive (less stable) than the unphosphorylated molecule.
- 7. A spontaneous chemical reaction in which there is a net release of free energy
- 8. A nonspontaneous chemical reaction in which free energy is absorbed from the surroundings.
- 10. The study of energy transformations that occur in a collection of matter
- 11. A process by which a chemical agent called a catalyst selectively increases the rate of a reaction without being consumed by the reaction.
