Enzyme Models Flashcards
What determines the reaction an enzyme is able to catalyze?
The enzymes shape and structure
What is the active site?
A special region of the enzyme which can join w/ specific substrates
What is the enzyme-substrate complex?
When an enzyme and substrate join together at an active site
What are the two models of the enzyme-substrate complex?
Induced fit and lock & key
What is the lock & key model?
When they fit perfectly together, like how a lock fits in a key
What is the induced fit model?
Substrates can change the structure of an active site to fit their shape
When the enzyme-substrate complex forms, what happens to the activation energy?
The activation energy is lowered, which allows for a quicker reaction
What’s released after the reaction takes place?
The products are released
What happens to the enzyme and active site after the reaction?
The enzyme can be reused and the active site is free to join with others with the same substrate
