|
Definition
|
|

|
Term
| What does induced fit mean when describing enzyme action? |
|
Definition
| When the active site changes shape to better fit the substrate after the substrate binds |
|
|
Term
| What is the affinity substrates have for the active site of an enzyme? |
|
Definition
|
|
Term
| What is the affinity products have for the active site of an enzyme? |
|

|
Term
| Name three type of enzyme inhibition |
|
Definition
| Competitive, non-competitive and feedback |
|
|
Term
| Describe how competitive inhibitors work. |
|
Definition
| Competitive inhibitors bind at the active site preventing the substrate from binding |
|
|
Term
| Describe how non-competitive inhibitors work. |
|
Definition
| Non-competitive inhibitors bind away from the active site but change the shape of the active site preventing the substrate from binding. |
|
|
Term
| The type of enzyme inhibition that can be overcome by increasing substrate concentration |
|
Definition
|
|
Term
| Describe feedback inhibition |
|
Definition
| The end product in the metabolic pathway reaches a critical concentration then inhibits an earlier enzyme preventing further synthesis of the end-product. |
