B1.2.4 - Enzyme Reactions Flashcards
1
Q
Name 3 factors that affect enzymes
A
- Temperature
- pH
- Enzyme/Substrate concentration
2
Q
How does temperature affect enzymes?
A
As it increases, the rate of reaction does as well
When it reaches its optimum, reactions works fastest
Anything beyond the optimum and the enzyme begins to denature and stop working
3
Q
How does pH affect enzymes?
A
Varies depending on what enzyme and how the pH affects each one
Works the same as temperatures though
Denatures after a certain pH (optimum)
4
Q
How does enzyme concentration affect enzymes?
A
It increases until it reaches the point where the substrate has been used up
In this case, it instantly denatures
5
Q
How does substrate concentration affect enzymes?
A
It increases and then at one point it plateaus due to another limiting factor
