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

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 of

EFFECT OF pH LEVEL ON THE ENZYME ACTIVITY OF INVERTASE John Dale Cruz‚ Michael Ray Dela Cruz‚ Karen Angelica Domalaon‚ Abegail Dulay‚ Shirley Ann Felipe Group 5 2C Medical Technology Biochemistry Laboratory ABSTRACT Invertase is a type of enzyme‚ a natural catalytic agent for biochemical reactions‚ can be obtained in Baker’s Yeast. Determination of the effect of pH on invertase activity is the primary objective of the experiment. Dinitrosalicyclic acid (DNS) Assay method is utilized to monitor

Objective: To investigate how pH affects the rate of protein digestion Hypothesis: I predict that since pepsin breaks down the material the quickest at a pH of 2 in the stomach‚ test tubes #3 will reduce the greatest because it has pepsin to further break down the egg. Whereas the other test tubes will have a smaller reduction. I think test tube #2 will have the second largest reduction rate and then #6 because they all will have a greater rate at breaking down the material‚ Then‚ I predict the

The Effects of a Seed Coat in Seed Germination Mario Monroe INT1 Task 3 The Effects of a Seed Coat in Seed Germination Abstract Seed germination is an important aspect in plants growth and food production. It is therefore it’s of uttermost importance to know the effective ways of seed germination so as to improve food production. This research was therefore prompted by the rising issue of farmers buying low quality and a damaged maize seed from unscrupulous sellers and this has led to deterioration

Effect of pH on Enzyme Activity Athenaa Jeyachandran Mr.Menes Course Code January 21st‚ 2013 The Effect on Enzyme Activity Due to Temperatures Purpose: The purpose of this lab experiment is to examine how different temperatures affect enzyme activity using hydrogen peroxide. Hypothesis: My hypothesis for this experiment is that temperatures near body temperature is when enzyme activity will be at its highest. I believe this will occur because in our body‚ enzymes

How does pH affect the activity of the Amylase? Abstract: In my experiment I aimed to observe how ranging pH levels will affect the rate in which amylase will break down the starch molecules. I will be measuring the time it takes for the dark liquid to disappear and leave a yellow brown liquid to be shown‚ which would show that there is no starch present in the solution because it would have broken into maltose by adding amylase. Results did not fully demonstrate what we expected in our hypothesis

inner tegmen and outer testa. On the seed coat a scar (hilum) is present which shows the place of attachment of a seed in the fruit is present. At one end of the hilum is the micropyle. Through micropyle the seed absorbs water during the process of germination. The embryo consists of epicotyl‚one or two seed leaves called cotyledons‚ and a hypocotyle. The portion of the embryo above the point of attachment of cotyledons to embryo axis‚ and below the plumule is called epicotyl. The plumule forms shoot

Seed Germination Some people‚ when they think of germination‚ think of a seed sprouting. Very plain‚ simple image in their mind‚ especially since there is so much more going on in the small seed. New Life is growing. Germination is the sprouting of a seed‚ through which a lot of plants reproduce‚ though not all. Water is a major trigger in the germination stage‚ playing a major role also later in the plant’s life. Though seeds are not the only way for plants to reproduce‚ it is one of the easiest

pH Affecting on Amylase Enzyme Is there a difference in the concentration of pH in the amylase enzyme activity? The null hypothesis would be that there will be no difference in the concentration of pH and alternative hypothesis would be that there will be a difference in the concentration of pH. The predication if that there will be a difference in the concentration of pH. The pH affects on enzyme activities‚ one of the enzyme that was used in the process was amylase.
