Catalase

Abstract: Amylase in the body is used to break down polysaccharides into monosaccharides. The monosaccharides are simple sugars that are used to give the body energy. This effect was investigated in an experiment designed to show the breaking down of starch solution. A water bath was used to heat water up to 60oc. Pieces of dialysis tubing were wet and had starch solution put inside. Half of the measuring cylinders were filled with 60oc water, and the other half with 25oc water. Tests of the…

The effect that temperatures at 4°C, 23°C, 32°C, and 48°C , pH 3, 5, 7, and 9, the boiled extract, and hydroxylamine had on the peroxidase enzyme extracted from Brassica rapa. Emma O’Donoghue Fundamentals of Biology I Lab Professor William Olsen October 8, 2015 Abstract The purpose of this lab was to determine the effects that a number of factors had on enzyme activity. The enzyme used during this lab was peroxidase, which was extracted from the organism Brassica rapa. The…

The purpose of this lab is to find the optimal pH of the enzyme peroxidase, which is found in plant and human cells as a byproduct of photorespiration, photosynthesis or cellular respiration. This is significant because an enzyme operating in nonoptimal pH could have negative effects on the cell, and could pose a health threat to the organism. Enzymes proteins that speed up chemical reactions by lowering the activation energy. They do this by acting as a template for substrate orientation,…

Enzymes are a biological catalyst. When a chemical reaction is taking place the enzyme works to lower the activation energy of a reaction. The activation energy is, the amount of energy that is required in order for a reaction to take place. Enzymes bind to reactant molecules. The enzymes hold these molecules in a way that makes the processes of the chemical bond-breaking and bond-forming take place more readily. A reaction can be either energy-releasing or energy-absorbing. Enzymes have no…

HALDANE RELATIONSHIP AND ONE-WAY ENZYMES  INTRODUCTION: Most of the enzyme catalyzed biological reactions are reversible in nature. However, an enzyme may prefer to catalyze the reaction more efficiently in one direction over the other under given physiological concentrations of substrate or product (substrate in the reverse direction). An enzyme favouring a virtual unidirectional catalysis of an overall reversible reaction can’t escape the laws of thermodynamics. As a catalyst doesn’t change…

Enzymes are proteins that are a efficient catalyst for a biochemical reaction. It’s responsible to speed up reaction by having an alternative pathway of low active energy. In a simple cell it can be found 2000 different enzymes, each one of these have the ability on catalyzing a different reaction. Each of the enzyme found are responsible on having a reaction occurring in the cell. In this certain reaction in the cell, the cell will tend to make poisonous chemical that could be harmful to the…

Chemical reactions are vital to living cells. Many chemical reactions take long periods of time to transpire. Enzymes serve as catalysts to speed up biochemical reactions in other substances. Each enzyme interacts with only one specific substrate (molecule) in an organism or a family of related molecules. Enzymes are not changed or used up by the reactions they catalyze, but their effectiveness can be influenced by environmental factors such as the pH level of an environment. All enzymes have an…

Objective: To understand the function of an enzyme when it undergoes different conditions such as temperature, PH, and concentration of the enzyme. Introduction: In our lab “Enzyme Action” we were testing the enzyme reaction with different substrates. In our lab we tested 3 different enzymes and substrates to find out when they are at the highest potential. Enzymes are necessary for life because they keep our bodies chemical reactions at a normal pace. Enzymes have the ability to keep a human…

ABSTRACT: Enzymes are catalysts, speeding up of chemical reactions, of biological systems by lowering the activation energy (Transitioned from the AP Biology Lab Manual). In addition, in order to determine the rate of an enzymatic reaction, one must measure a change in the amount of at least one specific substrate or product over time. We were curious about determining the effects of pH and heat on enzymatic activity because these are factors that usually affect the shape of an enzyme. We…

In recent studies, cyanide poison is a toxic substance that appears in different variety of crops. According to Ogundele and Caxton- Martins," Cassava is the most widely consumed of these plants and it has been associated with economic condition in certain parts of the World; especially the tropics and sub tropics." These plants are called cyanophoric plants because they contain phytotoxins. Cyanide is very highly reaction to alkali earth metal. They mostly reactive to salt such as potassium,…
