The effects of pH on mung beans Gloria Cheng Winsy Cheung Lily Wong Christine Yen January 15‚ 1998 Abstract This experiment explores how different pH environments affect the growth of mung beans. The mung beans were grown in water with various pH levels‚ consisted of pH levels 5‚ 6‚ 7‚ 8‚ and 9. A replicated design was used consisting of 3 runs for each pH level. The following results are listed in order of pH levels allowing most growth to least growth of the mung beans: 7‚ 8‚ 6‚ 5‚ and 9. These

Title : THE EFFECT OF PH ON THE ACTIVITY OF CATALASE Aim : To study the effect of pH on the activity of catalase. Introduction : Catalase‚ an enzyme found in many different tissues‚ catalyses the breakdown of hydrogen peroxide into water and oxygen. 2 H202 → 2H20 + O2 Hydrogen peroxide is a toxic substance that can be formed during aerobic respiration and catalase removes this product. The activity of catalase can be measured by finding the rate of oxygen release from hydrogen peroxide
