stack5/Enzymes
| Question | Answer |
|---|---|
| Enzymes | are substances that cause chemical reactions to occur faster |
| How do enzymes work | by decreasing the amount of energy needed to activate the chemical reaction |
| substrates | Ribosomes produce specific enzymes to act on specific substances |
| active sites | matches folds in the substrate’s surface |
| what are catalyzed? | Many of the chemical reactions that occur in cells |
| what is the function of enzymes in biological system? | speed up reaction |
| explain the importance of shape to enzyme function. | allows to bind to one substrate |
| explain why enzymes are specific | one enzyme=one substrate |
| an example of enzymes and why they are specific | lock and key, for a lock to have a key the have to be exactly for it to work |
| The shape of an enzyme determines how | it works |
| Most enzymes have a surface | with one or more deep folds |
| Many of the chemical reactions that occur | in cells are catalyzed by enzymes |
| Ribosomes produce specific enzymes to | act on specific substances, called substrates |
| If its shape is changed | the enzyme may not function as well or at all |
| what can affect an enzyme | Changes in temperature and pH can affect the shape of an enzyme’s active sites. |
| explain why enzymes con be reused over and over again | they are not change by reactions |
| why is there only one kind of enzyme for each biochemical reaction? | specific |
| how do extreme ph and extreme temperature affect enzymes? | change the shape, not work, denature |
