| In cells you add energy to reactions and these are | called coupler reactions |
| 3 ways you can add energy to reactions | 1. Add ATP, 2. Use Co-enzymes, 3. Use enzymes |
| Coenzymes | are not proteins. A coenzyme is a nucleotide plus a vitamin portion (example NADH, FADHs, NAD, FAd) |
| Enzymes | are proteins (which are catalysts-which mean they speed up reactions) |
| Many enzymes require | co-factors |
| Co-factors are | metal ions. |
| Examples of co-factors | zinc, copper, and iron |
| Sequence of a base | a gene |
| Mutagens | are radiation chemicals. They have the ability to change DNA |
| Excision repair | where DNA polymerase proofreads the DNA |
| Beadle and Tatum | discovered newrospora which is in bread mold and also figured out that one gene codes for one polypeptide chain |
| A gene is made of | hundreds to thousands of DNA molecules |
