Lab #6: pH Effects and Enzyme Concentration on Catecholase Activity Abstract: This experiment examined the effect on how the changes in pH balance of potato juice affected the enzyme activity‚ structural stability and solubility. Introduction: Enzymes are macromolecules that allow chemical reactions to occur. They function as biological catalysts. A catalyst is a substance that is involved in‚ but not changed by or consumed in‚ a chemical reaction. The amount of energy required for a reaction

Any experiences of prejudice and discrimination can affect children and young people in different ways‚ there are some cases where the effects are small but there may be cases where the effects and consequences can be very serious and will require the child or young person to have a lot of support from staff and outside agencies depending on the situation. When a child or young person experiences prejudice or discrimination they may have a lack of motivation‚ may become angry‚ depressed and confused

We are studying the effect of pH on catalase activity. Catalase by scavenging hydrogen peroxide to water and oxygen is an important enzyme of cell defense mechanisms against oxidative stress in all living organisms (Dat et al.‚ 2003). Cells use catalase because it is the most efficient enzyme as an antioxidative enzyme which lowers hydrogen peroxide or superoxide to accumulate to toxic levels in plant growth (Bowler et al. 1992). The formula that involves catalase as the enzyme is . pH is a measure

Positive Effects of Volcanos Volcanic activity has many positive impacts on both the natural physical environment and on socio-economic activity. Positive impacts include the creation of new land‚ the creation of valuable natural minerals and ores‚ and the enhancement of countries’ tourism potential. Creation of new land: Volcanic activity can result in the creation of new land‚ when material from within the earth’s crust is ejected in the form of molten liquid‚ then cools and solidifies to created
