PROPERTIES OF ENZYMES

    18.7: Enzyme Activity - Chemistry LibreTexts
  1.  All enzymes are proteins : This may seem rather odd, because some enzymes actually digest proteins.
  2. Enzymes are made inactive by high temperature : This is because they are protein molecules, which are damaged by heat.
  3. Enzymes work best at particular temperature : Enzymes which are found in the human body usually work best at about 37˙C. 
  4. Enzymes work best at a particular pH : pHis a measure of how acid or alkaline a solution is. Some enzymes work best in acid conditions (low pH). Others work best in neutral or alkaline conditions (high pH).
  5. Enzymes are catalysts : They are not changed in the chemical reactions which they control. They can used over and over again, so a small amount of enzyme can change a lot of substrate into product.
  6. Enzymes are specific : This means that each kind pf enzymes will only catalyse one kind of chemical reaction.

STEEL- MAKING

Image
                                                 The iron produced by the blast furnace is known as 'pig iron' or 'cast iron' and is not pure. It contains about 4% carbon, and other impurities. This amount of carbon makes the iron brittle. This limits the usefulness of the iron, though it can be cast (moulded) into large objects that are not likely to be subjected to deforming forces.        Most of the pig iron produced is taken to make steel. The carbon content is reduced by burning it off as carbon dioxide. Any sulphur contaminated is oxidised to sulphur dioxide. This basic oxygen process  is carried out in a tilting furnace. The method is fast: 350 tonnes of molten iron can be converted in 40 minutes. Scrap steel is added to the molten pig iron for recycling. A high-speed jet of oxygen is blown into the vessel through a water-cool...

THE STRAWBERRY PINK VILLA

Image
                                                      The villa was small and square, standing in its tiny garden with an air of pink-faced determination. Its shutters had been faded by the sun to a delicate creamy green, cracked and bubbled in places. The gardens, surrounded by tall fuchsia hedges, had the flower-beds worked in complicated geometrical patterns, marked with smooth white stones. The white cobbled paths, scarcely as wide as a rake's head, wound laboriously round beds hardly of stars, half-moons, triangles, and circles, all overgrown with a shaggy tangle of flowers run wild. Roses dropped petals that seemed as big and smooth as saucers, flame-red, moon-white, glossy, and unwrinkled; marigolds like broods of shaggy suns stood watching their parent's progress though the sky. In the low growth the pansies pushed their velvety, innocent faces t...
