Bio Unit 2 sec 1 #3
Bio Unit 2 Lecute 10: Enzymes
| Question | Answer |
|---|---|
| Proteins that facilitate reactions | Enzymes |
| Enzymes facilitate reactions by _______ the energy of the activation and then brining ______ together | Lowering; Substrates |
| Without enzymes, reactions in cells would not occur _____ enough or they would require too much _____ without enzymes | Quickly; Energy |
| _______ organisms could not _____ without enzymes | Living; Survive |
| Proteins are large _______ compounds | Organic |
| Enzymes have a specific 3-D structure that determines their _______ | Function |
| Loss of structure in an enzyme causes loss of function called: | Denaturation |
| The area on the protein that will interact with the substrate of a reaction is called the ______ | Active Site |
| When an enzyme encounters a substrate, the substrate will _____ into the ____ site and the interaction between enzyme and substrate causes a change in the substrate, causing the metabolic pathway to progress | Fit; Active |
| When a substrate bonds to a small area of the enzyme called the | Enzyme-Substrate Complex |
| When the substrate bonds to the active site in the Enzyme-Substrate Complex, the substrate now becomes ______ else | Something |
| An example of Enzyme-substrate Complex is ______ (table sugar) being broken ______ before it can enter the bloodstream after we eat a meal | Sucrose; Down |
| Enzymes are easy to identify because they end with "____" such as Sucrase | ASE |
| To change a substrate to another product, an _____ must be present | Enzyme |
| The slowing or stopping of metabolic pathways by inhibiting enzyme function is called: | Enzyme Inhibition |
| 2 kinds of Enzyme Inhibition are _____ and _______ Inhibition | Competitive; Non-Competitive |
| ________ inhibition is when the product of the metabolic pathway or another substrate binds/blocks the active site of the enzyme and keeps the substrate from using the enzyme, which slows or stops the chemical reaction | Competitive |
| ______ inhibition: the product of the metabolic pathway or another substrate binds an alternate site on the enzyme and CHANGES THE SHAPE of the enzyme's active so the site no longer binds to the substrate and decreases the amount of product produced | Non-Competitive |
| ______ inhibition is the use of a reaction product to regulate its own further production (non-competitive inhibition) | Feedback |
| Changes in temperature or Ph can ______ proteins because the chance can cause a change in the structure | Denature |
| The example of Enzyme-Substrate Complex with sucrose is the sucrose, which is the ______ interacts with Sucrase, which is the ______ and makes a new products (glucose + fructose) | Substrate; Enzyme |
