Temperature and pH on Enzyme Function Chelsie Mesa Section 0479 Robin Cotter Introduction The purpose of this experiment is to identify three unknown enzymes. This is done by using different temperature and pH to affect the function of the enzyme‚ which ultimately‚ will affect how much maltose is produced. Enzymes are proteins that help catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process are called substrates‚ and the enzyme converts them

Enzymes INTRODUCTION Enzymes are protein cells and they are found in the gut. They help to break down the food you eat. Enzymes are produced by living cells and they speed up reactions because they are biological catalysts. If we did not have enzymes‚ the reactions in our cells would be too slow to keep us alive. This means that they are extremely important for our survival. The properties of enzymes are: ⋆ They can be used many times‚ because they can speed up reactions without

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

Enzyme Reaction to Variable Elizabeth Alvidrez University of Texas at El Paso Abstract: An enzyme is a protein that serves as a biological catalyst (Denniston‚ 2007). Metabolic reactions happen with in cells. Enzymes are proteins that are used to speed up these reactions without being consumed by them (Mader‚ 2010). Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O (Campbell Reese‚ 2008). The environment plays an important role

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

temperature‚ pH‚ enzyme concentration‚ and substrate concentration on the reaction rate of an enzyme-catalyzed reaction. Another purpose of the lab was to explain how environmental factors affect the rate of enzyme-catalyzed reactions. Hypothesis: I believe that if there is an increase in enzyme concentration‚ an increase in temperature‚ or an increase in pH‚ then the intensity of the reaction will increase‚ which will cause greater alterations in the product of the reaction. I think this

the outcome of enzyme activity Introduction In this project I will monitor the rate of activity of Catalase. Catalase is an Enzyme which in the right conditions catalyses the decomposition of Hydrogen Peroxide into water and oxygen; 2H2O2 + Catalase >>> 2H2O + O2 Catalase is found in all cells and protects them from Hydrogen Peroxide which is a dangerous waste product that needs to be eliminated. Without Catalase living things could not survive. What are Enzymes? Enzymes are found in the
