| Question | Answer |
|---|---|
| what are enzymes | proteins (made up of amino acids) |
| Enzymes definition | speed up chemical reactions |
| another word for enzyme and definiton | catalysis- speed up chemical reactions without being changed or used up. |
| enzymes work with | co-enzymes (non proteins) |
| example of co enzymes are | vitamins |
| lock and key model | look at pic on paper!! |
| active site | the place where the chemical reaction takes place |
| substrate | the thing enzymes works on |
| examples of enzymes names (substrate+ase) | protease and lipase |
| protease | enzymes working on proteins |
| lipase | enzymes working on lipids |
| factors influencing enzyme action | pH, temperature, and concentration of enzymes and substrate |
| pH | each enzyme has an optimum(best) pH. (ex. on paper!!) |
| temperature | for many enzymes in humans the optimum temp. is 98.6 F(37C). |
| At temperatures above or below the optimum....: | the enzyme loses its shape(denaturation) and stops functioning.(ex. on paper!!) |
| concentration of enzymes and substrate | inc. concentration=inc, rate of reaction until it levels off.(ex. on paper!!) |
