Biology A level planning experiment of effect of lead ions on amylase
The effect of Lead ions on amylase activity
Aim
What is the effect of Lead ions on the enzyme Amylase. And does it have an inhibitory effect, which causes the substrate, in this case starch to be blocked from the reaction process in the enzyme catalyst. Also is the effect reversible or irreversible, which is put on the amylase.
Method
