The effect of substrate concentration on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase, produced by liver cells, on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction, the substrate binds to […]

Milgram’s Study of Obedience The name Stanley Milgram is eponymous with the study of obedience. In his controversial 1970s study of the human behaviour, Milgram (1974) discovered that when under direction from a member of authority, study participants could be instructed to inflict a 450 volt electric shock on another individual..
