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.

To investigate the effect of temperature on an enzyme controlled reaction Introduction and planning For the investigation of enzymes‚ I am going to conduct an experiment to see how temperature can affect the rate of reaction of enzymes by testing it with starch. The enzyme that we are going to use is called amylase. We are going to test this enzyme with starch. By mixing amylase and starch solutions together under different temperature conditions‚ we can record the rate of reaction by taking a
