Core component 4 - Reactions With Enzymes Flashcards
1
Q
How does any enzyme speed up the rate of reaction?
A
It provides an alternative pathway of lower activation energy (low temperature of cells)
2
Q
Why must enzymes be used?
A
The other way to make chemicals react is to increase their kinetic energy, however increasing temperatures above 40 degrees causes irreversible damage to proteins.
3
Q
Why does the graph showing formation of product against fime go through the origin?
A
Because at 0 time no reaction has happened yet
4
Q
How do you work out rate of production?
A
Increase in mass / time
5
Q
How do you work out rate of production from a graph showing mass of product produced against time?
A
You find the gradient of the graph at any point.
