Enzymes
| Question | Answer |
|---|---|
| What are enzymes? | are substances that cause chemical reactions to occur faster |
| What do enzymes do? | decreasing the amount of energy needed to activate the chemical reaction |
| What are enzymes also called? | A catalysts |
| What are many of the cells catalyzed by? | enzymes |
| Why are enzymes important? | cells would not be able to perform metabolism quickly enough to support life. |
| What are most enzymes made of? | proteins |
| What are enzymes produced by? | enzymes are produced by a cell’s ribosomes. |
| What are substrates? | specific enzymes to act on specific substances |
| What are enzymes also important for? | Enzymes are also important for the synthesis of new molecules |
| Example of the importance of enzymes. | For example, RNA polymerase is an enzyme that is essential to the process of transcription. |
| What does the shape of the enzyme determain? | determines how it works |
| What are the folds in an enzyme? | The folds make pockets, which are called active sites |
| What does the active site do? | The active sites match folds in the substrate’s surface. |
| What is teh enzymes shape? | An enzyme’s shape is key to how the enzyme functions. |
| What happens when an enzymes shape is changed? | the enzyme may not function as well or at all. |
| What can affect the change of the active site in an enzyme? | Changes in temperature and pH can affect the shape of an enzyme’s active sites. |
| When do enzymes work best? | enzymes are only able to work properly in a certain temperature and pH range. |
| What are RNA polymerase | is an enzyme that is essential to the process of transcription |
| Molecules of mRNA are..? | transcribed by RNA polymerases and later new protein molecules are synthesized based on the instructions coded in the mRNA. |
| What are factors of enzyme? | pH and tempurature |
| What happens to an enzyme when the active site isnt the same shape as the catalyst? | the enzyme doesnt work |
| What is a nick-name for an enzyme? | "work horse" of a cell |
| What is in an enzyme? | Lactase |
| What does an enzyme breakdown? | Lactose |
| What is it called when the active site combines with a substrait? | Lock and Key |
