Enzymes
| Question | Answer |
|---|---|
| What is the name for something, like an enzyme, that speeds up chemical reactions? | Catalysts |
| Would chemical reactions in the body still be completed without catalysts? | Yes |
| What macromolecule are enzymes? | Most enzymes are proteins |
| Where do the reactions assisted by enzymes take place in the body? | Cells |
| How many functions does each individual enzyme normally have? | Each type of enzyme usually has only one function. |
| How are enzymes named? | Enzymes are usually named based on their sole function or one reaction. |
| Do enzymes reduce or increase the needed energy at the active sites and why? | Enzymes reduce the needed energy to break bonds and rearrange them in order to speed up chemical reactions. |
| What are the reactants in an enzyme catalyzed reaction called? | The reactants in these reactions are called substrates |
| What bonds connect substrates to the active site of the enzyme? | Weak bonds, such as van der wall bonds or hydrogen bonds. |
| What factors affect the productivity of enzymes in the body? | Ph and temperature changes alongside the concentration of enzymes and substrates, and the presence of other substances |
| What is the connection between enzymes and having a fever? | When you have a fever you usually have a higher body temperature, which affects the usefulness of enzymes, affecting the body and making eating less appealing. |
| What is metabolism | The sum of all the chemical reactions that take place in the body |
| Anabolic reactions | small molecules and energy create larger molecules |
| Catabolic reactions | Larger molecules are broken down into smaller molecules and energy |
| Is an enzyme used only once? | an enzyme is used over and over again after a reaction, maltase can be used 1,000 times a second |
| What are inhibitors and what is their function? | Inhibitors take the place of a substrate, preventing the substrates desired reaction |
| What is competitive inhibition? | When the inhibitor binds to the active site of the enzyme, can be reversed by increasing the substrate concentration |
| What is non-competitive inhibition? | When the inhibitor binds to a non active site of the enzyme, and still blocks the reaction |
| What is it called when major changes in the environment of an enzyme change its shape, function, and functionality? | Denaturation |
| Can enzymes provide energy for a reaction? | Never |
| Do enzymes change after a reaction? | Nope |
| Do all enzymes end in -Ase? | yes |
