Enzymes Flashcards
1
Q
What are enzymes?
A
Proteins necessary for survival
Biological catalyst
2
Q
What are two types of enzymes?
A
- Intracellular (inside cells, metabolic reactions)
- Extracellular (outside cells eg. digestion)
3
Q
What is an active site?
A
Where the substrate attach’s to the enzymes surface
4
Q
What is the lock and key model?
A
The substrate molecule is an exact fit to the enzymes active site
5
Q
What is the induced fit model?
A
The substrate has no fixed shape and changes to fit into the active site
6
Q
What is a humans ideal temperature?
A
37*C
7
Q
What happens if an enzymes temperature increases?
A
An increased rate of reaction due to more collisions
if the temp is too high the active sight will denature
8
Q
What if the enzyme temp is too low?
A
The active sight does not denature but activity does slow down
