Aim To investigate the effect of different temperatures on the activity of rennin in milk Introduction Enzymes are globular protein‚ responsible for most of the chemical activities of living organisms. They are made up of long chains of amino acids containing carbon‚ hydrogen‚ oxygen and nitrogen (Gunsch‚ 2012). The role of enzyme is to act as catalysts‚ substances that speed up chemical reactions without being chemically altered during the process. The speeding up of chemical reactions is done

reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that specific enzyme. The place where the substrate fits and where catalysis occurs is known as the active site. The reason a specific enzyme will combine only with one kind of substrate is that the fit among the two is very precise. In fact‚ the fit is so precise‚ that the blend between the two results in a slight change

various building blocks can be controlled using the fundamentals of reticular chemistry. This offers a great potential for tailoring MOFs properties for a wide scope of high-tech applications (high-capacity adsorbents‚ membranes‚ thin film devices‚ catalysis‚ biomedical imaging‚ etc.). MOFs have traditionally been used for gas storage and separation‚ and much less attention has been devoted to their electronic properties3. This has changed in the past decade and MOFS with high electrical conductivity

Cofactors‚ mostly metal ions or coenzymes‚ are inorganic and organic chemicals that assist enzymes during the catalysis of reactions. In the performed experiment the cofactor used was Magnesium in the form of Magnesium sulfate (MgSO4). Two replicates were prepared‚ one with the cofactor and the one without. Since respiration produces carbon dioxide‚ the rate of cellular

Alkanes The reaction between alkanes and fluorine This reaction is explosive even in the cold and dark‚ and you tend to get carbon and hydrogen fluoride produced. It is of no particular interest. For example: The reaction between alkanes and iodine Iodine doesn’t react with the alkanes to any extent - at least‚ under normal lab conditions. The reactions between alkanes and chlorine or bromine There is no reaction in the dark. In the presence of a flame‚ the reactions are

synthesised by living cells. They are protein in nature (exception RNA acting as ribozyme) colloidal and thermo-labile in character and specific in their action. HISTORICAL BACKGROUND In 1878 kuhne used the word enzyme (Greek: in yeast) to indicate the catalysis taking place in biological systems. Isolation of enzyme system from cell free extract of yeast was achieved in 1883 by Buchner. He named the active principle as Zymase (later found to contain a mixture of enzymes)‚ which could convert sugar to alcohol
