Across
  1. 5. a reaction that requires energy to be absorbed in order for it to take place.
  2. 6. the capacity for doing work
  3. 8. a biochemical process in metabolism where the simple molecules combine to generate complex molecules.
  4. 11. model proposing that the binding of a substrate or some other molecule to an enzyme causes a change in the shape of the enzyme so as to enhance or inhibit its activity.
  5. 13. any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
  6. 14. the specific region of an enzyme where a substrate binds and catalysis takes place or where chemical reaction occurs.
  7. 15. an organic molecule that binds to the active sites of certain enzymes to assist in the catalysis of a reaction.
  8. 16. the minimum amount of extra energy required by a reacting molecule to get converted into a product.
  9. 17. is a biological molecule consisting of one adenine, one sugar, and two phosphates.
  10. 19. The measure of the disorder of a system
  11. 20. The chemical substances which are formed due to a chemical reaction between two or more chemical substances are called the products.
  12. 21. energy cannot be created or destroyed
  13. 23. a series of connected chemical reactions that feed one another.
  14. 24. Reactions that have a negative change in free energy and consequently release free energy
  15. 25. a group of substances that are needed for normal cell function, growth, and development.
  16. 26. a biological catalyst and is almost always a protein.
Down
  1. 1. a substance that takes part in and undergoes change during a reaction.
  2. 2. the part of the metabolic process that breaks down large, complicated molecules into smaller ones in order to produce energy.
  3. 3. a thermodynamic quantity equivalent to the capacity of a system to do work.
  4. 4. the energy possessed by a body by virtue of its position relative to other
  5. 7. a non- protein chemical compound that is bound to a protein and is required for the protein's biological activity.
  6. 9. is the source of energy for use and storage at the cellular level.
  7. 10. energy which a body possesses by virtue of being in motion.
  8. 12. When two reactions are coupled, they can be added together to give an overall reaction
  9. 18. when a molecule binds an enzyme and prevents it from carrying out a chemical reaction.
  10. 22. are catalytically active RNA molecules or RNA–protein complexes, in which solely the RNA provides catalytic activity.
  11. 23. the chemical reactions in the body's cells that change food into energy.
