Substrate concentration Flashcards
1
Q
The higher the substrate concentration…
A
The faster the reaction
2
Q
More substrate molecules means a…
A
Collision between substrate and enzyme is more likely and so more active sites will be used
3
Q
This is only true up until a ‘saturation’ point though, after that…
A
There are so many substrate molecules that the enzymes’ active sites are being used up
4
Q
Therefore the addition of further substrate molecules has…
A
No effect as all active sites are already occupied at one time, so no increase in the rate of reaction
