Practical Assessment 2 – The effect of substrate concentration on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site

How Hormones Effect the Endocrine System Introduction: The endocrine system primarily relies on the negative feedback mechanism. The endocrine system influences metabolic activities by sending out chemical messengers through the blood called hormones. Once released into the blood these hormones are transported throughout the body. The effects of these hormones are wide spread and vary from reproduction‚ growth and development‚ immunities‚ maintaining electrolyte levels‚ water and nutrient balance

How does the temperature of water affect how fast sugar can dissolve? Predict We will do three different tests‚ dissolving the water in boiling‚ warm and cool water. The sugar in the boiling water will dissolve the fastest. The sugar added to the cool water will dissolve the slowest. Reason According to the state of matter theory‚ the particles in a gas move faster than in a liquid‚ which I will use to infer that the hotter the water is and closer to a gas‚ the faster the particles move. Therefore
