    Effect of concentration on Urease Activity

    I need some help understanding the relationship between enzyme and substrate concentration insofar as measurable enzyme activity is concerned? What would be the results? Effect of Temperature on Amylese Activity. What do you think would be the optimum temperature for Amylase?

    Uncoupling of Electron Transport by MDMA

    MDMA is a popular club drug. It works on a different part of the electron transport chain, however. It is an uncoupler, which means that is still allows energy to be produced but not used by the body. Where will this energy go? How will this manifest in a person that has taken the drug?
