314.2 Enzymes Flashcards
1
Q
What is an enzyme?
A
Biological catalyst
2
Q
How do enzymes catalyse a reaction?
A
By bending/forming bonds
3
Q
What is the difference between the lock and key model and the induced fit model?
A
Lock and Key: Enzymes and substrates were rigid structures that precisely locked into each other.
Induced Fit: Conformational changes occur when the enzyme and substrate molecule interact, ensuring an ideal binding arrangement and maximizing the enzyme’s ability to catalyze the reaction.
