Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from

There are many reasons why enzymes have such a high specificity. The first variable is an enzyme’s primary structure. A primary structure is just a combination of amino acids. There are twenty different amino acids that the primary structure can be created from. Every enzyme has a different order that the acids are placed in and each one has a different number or amino acids. The slightest change in this structure can affect a protein’s conformation and function. The secondary structure is a regular

Computer Enzyme Action: Testing Catalase Activity 6A H2O2 is toxic to most living organisms. Many organisms are capable of enzymatically destroying the H2O2 before it can do much damage. H2O2 can be converted to oxygen and water‚ as follows: 2 H2O2 → 2 H2O + O2 Although this reaction occurs spontaneously‚ enzymes increase the rate considerably. At least two different enzymes are known to catalyze this reaction: catalase‚ found in animals and protists‚ and peroxidase‚ found in plants. A great

HOW CANCER CELLS WORK A diagnosis of cancer can be devastating. And there is good reason for this fear -- Cancer is the second leading cause of death in the United States next to heart disease‚ and will claim more than half a million lives this year. Cancer also known as a malignant tumor or malignant neoplasm‚ is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. Not all tumors are cancerous;benign tumors do not spread to other

its enzymatic activity? Answer: As protein kinase and protein phosphatase are the enzymes‚ they both perform their enzymatic activity by interacting at the specific binding site on the protein. Both of the enzymes recognize the specific amino acid sequence around the amino acid that is to be either phosphorylated or dephosphorylated respectively. 6. Why would a signaling pathway need to be regulated? Answer: Signaling pathway needs to be regulated because if not regulated‚ it would leads

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

Enzyme are a very important component in living organisms. If enzymes did not exist than life itself would not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not

Enzyme Catalysis Abstract: Catalysis is an enzyme that decomposes hydrogen peroxide into oxygen and water. In this lab we will conduct a series of experiments to determine the affects of; pH‚ temperature‚ and concentration change on such catalysis. After completing the experiments we determined that catalase works most efficiently when in a 27°c‚ 50% (5 ml of catalase – 5ml of water)‚ and a normal body pH of 7°.

Effect of the Changes in the Environment to the Functionality of the Enzymes Introduction a. Background In our everyday lives‚ enzymes are used in our bodies‚ and in nature around us‚ to speed up the chemical reactions happening constantly‚ which happens by lowering the amount of activation energy needed to start various reactions. The way this works is by attaching the particular substrate to the active site of the enzyme‚ where it will start to aid the chemical reaction. Then‚ the allosteric
