Potato Batteries: Veggie power! Data and Analysis Background The battery was invented around 1800 by Alessandro Volta in Italy. It has become an indispensable part of modern life. Why are batteries so useful? Because they convert chemical energy into electrical energy. You can use this electrical energy to light a flashlight‚ to start a car‚ or to listen to your favorite music. We made a simple battery out of a potato by placing in it a zinc strip and a copper strip. At the zinc strip‚ the

Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product

This Chip Can Tell If You’ve Been Poisoned Quick detection. This 2-cm-wide chip (inset) can quickly test for botulism‚ a deadly disease caused by theClostridium botulinum bacterium. When you are dealing with a deadly poison that can be found in food and is a potential terrorist weapon‚ you want the best detection tools you can get. Now‚ researchers in France have demonstrated an improved method to detect the most deadly variant of the botulinum neurotoxin‚ which causes botulism. Their test

general-purpose design which has its own advantages and disadvantages. ➢ Adv: One chip can run a range of programs. That ’s why you don ’t need separate computers for different jobs‚ such as crunching spreadsheets or editing digital photos ➢ Disadv: For any one application‚ much of the chip ’s circuitry isn ’t needed‚ and the presence of those "wasted" circuits slows things down. Suppose‚ instead‚ that the chip ’s circuits could be tailored specifically for the problem at hand--say‚ computer-aided

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The
