| Front |
Define inactive precursor enzyme and explain why enzymes may be produced in this form. |
| Back |
Inactive precursor enzyme - enzyme that requires biochemical change for it to become active- Used to prevent some enzymes from causing damage within cells producing them/tissues where realeased
- Used when an enzyme's action needs to be controlled and only activated under certain conditions
Example: - Used to prevent proteases from digesting membrane proteins in vesicles storing them which would result in vesicles breaking down, prevent proteases from digesting other enzymes
- Trypsinogen and pepsinogen are inactive forms of trypsin and pepsin, used this way
