1.7 Enzyme Action Flashcards
1
Q
What are enzymes?
A
Globular proteins that act as catalysts
2
Q
What does activation energy mean?
A
Minimum amount of energy needed to activate a reaction
3
Q
What is the induced fit model?
A
Enzyme is flexible and can alter in the presence of a substrate
4
Q
How can the induced fit model lower the activation energy?
A
- Puts a strain on substrate
- Distorts substrate bonds; lowers activation energy
5
Q
What is the lock & key model?
A
Substrate (key) exactly fits the enzyme (lock)
