Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

why they are so important. The complete active enzyme with its cofactor is called a holoenzyme‚ while just the protein part without its cofactor is called the apoenzyme. How do enzymes work? There are three parts to our thinking about enzyme catalysis. They each describe different aspects of the same process‚ and you should know about each of them. 1. Reaction Mechanism In any chemical reaction‚

3. Results and discussions 3.1. Disease Severity Results presented in Table 2 showed the disease severity (PDS) after 15 d of inoculation. A significant difference in the PDS was noticed between ‘Nicola’ and ‘Spunta’. The resistant cultivar (Nicola) showed lower incidence of infection compared to the susceptible cultivar (Spunta). Inducers’ treatments individually or in combination with difenoconazole (fungicide) showed significant protective effects against A. solani. The 2‚4-D was the most
