Down
- 1. a substance that takes part in and undergoes change during a reaction.
- 2. the part of the metabolic process that breaks down large, complicated molecules into smaller ones in order to produce energy.
- 3. a thermodynamic quantity equivalent to the capacity of a system to do work.
- 4. the energy possessed by a body by virtue of its position relative to other
- 7. a non- protein chemical compound that is bound to a protein and is required for the protein's biological activity.
- 9. is the source of energy for use and storage at the cellular level.
- 10. energy which a body possesses by virtue of being in motion.
- 12. When two reactions are coupled, they can be added together to give an overall reaction
- 18. when a molecule binds an enzyme and prevents it from carrying out a chemical reaction.
- 22. are catalytically active RNA molecules or RNA–protein complexes, in which solely the RNA provides catalytic activity.
- 23. the chemical reactions in the body's cells that change food into energy.
