Before toy start this section, write the section title, purpose and a hypothesis on your lab paper. 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. The initial rate of reaction is when concentrations of enzyme and substrate are known, so this allows fair comparison if you then change initial concentrations of enzymes or substrate. Once you have multiple reaction rates at different substrate or enzyme concentrations, it is then possible to take this one step further and plot reaction rate ... Besides measuring the products (in this lab, the amount of oxygen gas released by the reaction), enzyme activity can be measured by recording the decreasing water level in the test tube. As oxygen gas is released from the dropper as a product of the reaction, it rises into the test tube, displacing the water in thetube.Wholesale coin auctions
