How does temperature affect enzyme activity?
The particles vibrate more and if they vibrate too much they break the bonds that hold enzymes together. This means the active site changes shape so the reaction can't be catalysed.

How does pH affect enzyme activity?
Above and below optimum pH the hydrogen and ionic bonds break.
2 of 5
How does concentration affect enzyme activity?
Increases to a certain point until no substrate is available they have no effect.
3 of 5
How does substrate- concentration affect the rate of enzyme activity?
It increases to a certain point until all the active sites are full.

How to measure rate of enzyme activity?
Add catalase to hydrogen peroxide and it will break down to water and oxygen.
