Term
|
Definition
| Accelerate the conversion of substrates to products by forming induced-fit enzyme substrate complexes which speed chemical reactions. They do this by lowering the activation energy. |
|
|
Term
| In the experiment, what was the enzyme, substrate, and products? |
|
Definition
Enzyme: Catalase in Liver Extract (Catechol Oxidase)
Substrate: Hydrogen Peroxide (H2O2)
Products: Water and Oxygen (Benzoquinone) |

Term
| How are enzymes effected? |
|
Definition
1.) pH - 7
2.) temperature -
3.) substrates
4.) cofactors |
|
|
Term
|
Definition
| Lowers the amount of energy necessary for a chemical rxn to occur. |
|
|
Term
|
Definition
| The substance being acted upon. |
|
|
Term
| Substrate + Enzyme = Enzyme-Substrate Complex -> Products + Enzyme |

Term
| What does denaturation mean? |
|
Definition
| a structural change in macromolecules caused by extreme conditions |
|
|
Term
| what happened in our experiment when enzyme concentration increased? |
|
Definition
| The rate of reaction increased. As long as the enzyme does not outnumber the amount of substrate this will remain true. |
|
|
Term
| What happened when the pH was changed between 4, 7, 10? |
|
Definition
| The optimal pH is 7 so that is the pH where the reaction occurred the fastest. |
|
|
Term
| What happened with temperature? |
|
Definition
| The reaction occurred quickest at 37 C because that is closest to body temperature. Any lower or higher can denature it. |
