Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

In this lab‚ we added a buffer solution composed of salt‚ clear dish detergent‚ and deionized water for procedure 1( the strawberry part). For procedure 2( our cheek cells)‚ we used the same buffer solution but added red food coloring so we can distinguish the DNA from the rest of the cellular components because it was all a white mixture
