Lab 5 Enzyme Flashcards
1
Q
catalyst
A
An agent that speeds up the rate of a chemical reaction without being consumed during the reaction
2
Q
Enzymes
A
Protein catalyst in living cells
3
Q
Enzymes
A
Increase the rates of chemical reactions by lowering activation energy
4
Q
Active site
A
location in enzyme where reaction takes place
5
Q
substrate
A
reactants that bind to activate site
6
Q
Enzyme-substrate complex
A
Formed when enzyme and substrate bind
- lock and key metaphor- only the right key (substrate) will fit the lock (enzyme)
7
Q
Factors that affect enzyme activity
A
- denaturation: change in the shape of enzyme
- temperature and pH changes can denature enzymes
