Substrate Concentration Flashcards
1
Q
What is the independent variable?
A
Can be changed (x axis)
2
Q
What is the dependent variable?
A
Can be measured (y axis)
3
Q
Low substrate concentration means…
A
Only a few substrate molecules bump into an enzyme molecule
Reaction rate: LOW
4
Q
When substrate rate increases…
A
Rate of reaction increases, as more enzyme molecules have their active sites filled with substrate molecules
5
Q
When substrate concentration increases further…
A
Substrate molecules have to wait for a free active site
Reaction rate: STARTS TO LEVEL OFF
6
Q
When the concentration is high…
A
All of the active sites are full, so substrates must wait.
Reaction rate: MAXIMUM
