Enzymes Flashcards
1
Q
How do enzyme increase the rate of reaction?
A
They lower the activation energy of the reaction they catalyse.
2
Q
What is the active site?
A
- The area of the enzyme where the reaction with the substrate
takes place.
Only one specific substrate fits into the active site of the enzyme.
3
Q
What is the induced fit model?
A
A complex is formed by the enzyme and substrate.
The structure of the enzyme is altered to complement the substrate so that the active site of the enzyme fits.
4
Q
How does enzyme concentration effect enzyme action?
A
Rate of reaction is increased.
5
Q
How does substrate concentration effect enzyme action?
A
6
Q
How does temperature effect enzyme action?
A
7
Q
What is an inhibitor?
A
a substance which slows down or stops a reaction by affecting the binding of
substrate to the enzymes. Inhibitors can either be reversible and irreversible.
