| Question | Answer |
|---|---|
| Anabolism | Metabolic process, larger molecules are synthesized from smaller ones. |
| Catabolism | Metabolic process, breaks down large molecules into smaller ones. |
| Dehydration Synthesis | Anabolic process, joins small molecules by releasing the equivalent of a water molecule (synthesis). |
| Hydrolysis | Enzymatically adding a water molecule to split a molecule into smaller portions. |
| Substrate | The substance upon which an enzyme acts. |
| Active Site | Region of an enzyme molecule that temporarily combines with a substrate. |
| Enzyme | A protein that catalyzes a specific biochemical reaction. |
| Cofactor | A small molecule or ion that must combine with an enzyme or activity. |
| Coenzyme | A non protein substance that is necessary for the activity of a particular enzyme. |
| Oxidation | Process by which oxygen is combined with another chemical; the removal of hydrogen or the loss of electrons; opposite of reduction. |
| Cellular Respiration | Process that releases energy from organic compounds in cells. |
| Glycolysis | The breakdown to pryuvic acid during cellular respiration. |
| Citric Acid Cycle | A series of chemical reactions that oxidizes certain molecules, releasing energy (Krebs Cycle). |
| Electron Transport Chain | A series of oxidation-reduction reactions that takes high energy electrons from glycolysis and the citric acid cycle to form water and ATP. |
| Phosphorylation | Metabolic process that adds a phosphate to an organic molecule. |
| Transcription | Manufacturing a complementary RNA from DNA. |
| Translation | Assembly of an amino acid chain according to the sequence of base triplets in an mRNA molecule. |
| Codons | A set of three nucleotides of a messenger RNA molecule corresponding to a particular amino acid. |
