Inhibition of YADH Aim The aim of the experiment is to investigate the inhibitory effects of acetaldehyde. Principle: According to Palmer (1991)‚ “an inhibitor is a substance decreases the rate of an enzyme catalysed reaction”. The binding of inhibitors normally affects the activity of an enzyme. Enzyme inhibition studies are important because most poisons and drugs achieve their effects by inhibiting cell. Enzyme inhibition is also an important phenomenon in the cell metabolism because allows

Redox Titration Analysis of a Commercial Bleach Purpose To perform a redox titration. To determine the amount of hypochlorite ion present in commercial bleach. Introduction Many commercial products‚ such as bleaches and hair coloring agents‚ contain oxidizing agents. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (sometimes written NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized

Title: Redox Reaction Introduction: Some of the most important chemical reactions are Redox reactions. They are also known as oxidation-reduction reactions. This reaction passes one or more electrons from one species to another. The species that loses electrons are being oxidized while the species that gains electrons are reduced. The reaction occurs simultaneously. Numbers are given to each element in a chemical reaction to help us find out which element is oxidized and which is

down starch in solutions that are increasing in neutral pH. To do this the experiment was carried out so that tubes containing a reaction solution of the Amylase enzyme and starch were simultaneously mixed. The reactions were then introduced to I2-KI‚ which stopped the reactions‚ at two minute intervals. Each of these trials was repeated three times to ensure proper accuracy. After concluding the reactions they were placed into a spectrophotometer (A580) for analysis. Graphing the values of the

the solution. The tip of the buret was checked to make sure there weren’t any bubbles in it. Then a 250mL beaker was obtained. A 25mL pipette was used to add exactly 25mL of the KIO₃ solution. Then 50mL of deionized water and about .25g of solid KI was added. The solution was stirred until the solid was completely dissolved. 2mL of glacial acetic acid was then added.

Szegény Gélyi János lovai című novella elemzése „Megérti a négy okos állat a parádét…” A környezet‚ a természet legapróbb részletei is zseniálisan alátámasztják‚ olykor megindokolják‚ vagy kiegészítik a cselekmény folyamát Mikszáth novelláiban. A büszke‚ boldog lovak kicicomázott parádéja Gélyi János érzésének metaforája. Ez a metafora – Gélyi érzéseinek és a lovaknak párhuzama – végigvonul az egész művön.
