Enzyme Function Flashcards
1
Q
What is an enzyme?
A
A protein that catalyzes biochemical reactions by lowering activation energy.
2
Q
What is the active site of an enzyme?
A
The region where substrate molecules bind and undergo a chemical reaction.
3
Q
How do enzymes increase reaction rates?
A
By stabilizing the transition state and reducing activation energy.
4
Q
What factors affect enzyme activity?
A
Temperature, pH, substrate concentration, and the presence of inhibitors or activators.
5
Q
Give an example of an enzyme and its function.
A
Lactase breaks down lactose into glucose and galactose, aiding digestion.
6
Q
What happens to an enzyme after a reaction?
A
The enzyme remains unchanged and can catalyze additional reactions.
