An experiment to show effect of the temperature on the action of an enzyme Abstract The experiment was to analyse what reaction temperature would have on Amylase enzyme. We heated alpha amylase solution to set temperatures then tested for the presents starch with iodine solution. Any starch would turn the iodine black. Once the starch had broken down the iodine would remain brown to suggest the presents of maltose. Usually I would expect to find that the reactions would increase as the temperature

The purpose of the enzyme lab conducted was to observe the chemical composition of cells. In order to do so we tested for the presence of organic molecules. Molecules are what forms when atoms bond together. Organic molecules of cells include proteins, carbohydrates, and lipids, which are composed of smaller molecules known as monomers and polymers. Polymers are joined monomers. A chemical reaction links monomers together occurs and releases a water molecule, this is called dehydration synthesis

Enzyme Lab INTRODUCTION: What would happen to your cells if they made a poisonous chemical? You might think that they would die. In fact, your cells are always making poisonous chemicals. They do not die because your cells use enzymes to break down these poisonous chemicals into harmless substances. Enzymes are proteins that speed up the rate of reactions that would otherwise happen more slowly. The enzyme is not altered by the reaction. You have hundreds of different enzymes in each of your cells

Question 1 List and provide a brief discussion of the seven categories of toxic responses that a biological system may have. . There are seven categories of toxic responses: • Acute toxicity. This category is related to the immediate toxic responses that every biological system may have. This exposure of toxic substances for shorter duration and the diverse effect is high • Sub-chronic toxicity. This group results from exposure that is recurring numerous times. It is an ordinary human exposure

Title: Enzyme Introduction The main reason for conducting this experiment is to establish the various factors that affect enzymes and reaction rates. Various experiments have been conducted to help gain a wide range of the factors that affect enzyme controlled reactions. Enzymes are affected by very many factors. It was the main aim of this experiment to establish these factors and the manner in which they affect them. This experiment also seeks to establish the manner in which some enzymes

Whey protein Whey protein is basically the protein contained in whey, the watery portion of milk generated as a result of producing cheese. Once considered a waste by-product, dairy companies now understand and recognize its benefits, resulting into its concentration and purification. Being an abundant source of branched-chain amino acids (BCAAs), it is used to stimulate protein synthesis. It includes these three amino acids: leucine, isoleucine, and valine. These three have been proven to be

Recording Electrodes used in the Biomedical Instrumentation: Recording electrodes are the devices that convert ionic potentials into electronic potentials. The type of electrodes used for the measurements depends on the anatomical location of the organ. Bio-electrodes are the sensors that convert ionic conduction into electronic conduction. The purpose of bio-electrodes is to acquire bioelectrical signals such as ECG, EMG, and EEG, etc. Electrodes are mainly classified into two types [20]: 1. Perfectly

Enzymes are natural catalysts - substances that speed up a rate of reaction without being used up. They are also proteins that are molded into various shapes that allow substrate molecules to fit inside them. The region where the substrate molecules insert themselves is called the active site. Without enzymes, biological reactions would take excessive time to take place to keep you alive. They are also significant as they aid cells to connect with one another allowing cells to maintain growth, life
