To Investigate the Effect of Hydrogen Peroxide Concentration
634 words 2 pages

To Investigate the effect of hydrogen peroxide concentration on enzyme catalase Indroductlon: Enzymes are proteins. They function as biological catalysts. They lower the energy barrier of a reaction so that the reaction can take place at body temperature. Also, they can speed up Metabolic reactions without being changed or used up. During a reaction, an […]

It has the following equation: 2H202 (l) 2H20 (l) + 02 (8) This reaction does occur spontaneously at room temperature with the presence of ltraviolet light; however only very slowly. It occurs far faster when a catalyst is used. Catalysts are substances that speed the rate of a reaction without getting involved in the reaction […]

For this investigation, we are going to find out how different enzymes (in this case, trypsin) concentration in a solution would affect the rate of which solute (Casein) is broken down. I think enzyme concentration would definitely have an effect on the rate of reaction. My hypothesis is that increasing the concentration of trypsin would […]

I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts – catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific […]
