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 like Catalase affect the rates of reactions (Cohnheim 2009). Methods To establish

Title of the article: Intractable hyperkalemia due to Nicorandil induced potassium channel syndrome Abstract: Nicorandil is a commonly used antianginal agent which has both nitrate-like and ATP-sensitive potassium channel activator properties. Activation of potassium channels by nicorandil causes expulsion of potassium ions into the extracellular space leading to membrane hyperpolarisation, closure of voltage-gated calcium channels and finally vasodilatation. However, on the other hand, being

and other reagents used in the synthesis and work-up of isobutyl isobutyrate. The synthesis reaction of isobutyl isobutyrate was monitored by Mini – Gas Chromatography in order to monitor the progression of reactant to product. Mini-GC is a very valuable way to evaluate the progress of a reaction for which Thin Layer Chromatography (TLC) can not be used, while still only requiring a small sample of the reaction mixture. The isobutyl isobutyrate was separated via liquid/liquid extraction and purified

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

2.1.3 Application of biosurfactants Biosurfactants are important in petroleum, environmental, food, agricultural, bioprocessing, cosmetics and biological industries (Fakruddin, 2012; Nitschke & Costa, 2007; A. Singh et al., 2007). Table 2.2 shows the role of biosurfactants in different industries (A. Singh et al., 2007). Table 2.2 : The role of biosurfactants in various industries 2.2 Actinomycetes 2.2.1 Properties of actinomycetes Actinomycetes are the intermediate group between bacteria and fungi

Abstract The experiment is done to determine which type of word association will elicit shorter time and which will elicit more response word. The class was divided into groups with three members; each will take place as the experimenter, recorder and experimenter with the same set of stimulus words. Each undergoes with the three sets of stimulus words. Set one is free associated with 60 stimulus words, set two includes 15 stimulus words and set three has 5 original stimulus words. Results including

sculpture The American Woman was made of bronze. The work of art has streaks of a striking blueish green color and gives the appearance of painted metal. But as a viewer would notice as he or she got closer is that the color is really due to a chemical reaction, a result when bronze is in contact with water and oxygen. The statue is a smooth texture and with abrupt curves to convey the basics of a woman’s figure. A critic requires a closer and longer look of Hostetler’s work to understand that it is not

of water as a reaction medium or additive to enhance reaction efficiency is an important topic in green chemistry, and ring opening and contraction reactions of aromatics are crucial for upgrading diesels. In this work, we investigated the effect of water on the yields of ring opening and contraction reactions. A series of catalysts, such as Rh2O3/HY zeolite, Mo-Ni oxide and their physical mixture, were used as the catalysts. The influences of water amount, hydrogen pressure, reaction temperature and

Hypertension, insomnia, heart attack, headache, hyper-acidity and skin problems are among the common health problems associated with fury (Collins). Anger is an innate and a natural reaction a person has. It is not wrong to become mad and it is unavoidable to have an extreme reaction towards some situation. Anger should only
