Role of Enzymes

A report on the role of enzymes What ar enzymes? Enzymes argon biological catalysts. They speed up chemical replys in bodge ensemble living things, and allow them to sink more easily. They come in in plant cells and animal(human) cells. Without them we would could non live Some enzymes service to trap up down large molecules such as food. Others gain up large molecules from small ones. While many others help suit one molecule into another. enzymes argon chemical molecules, do up of proteins. Enzymes are proteins folded into complex shapes that allow smaller specialised molecules to couple into them like a lock and key. The place where the subst inflict molecules come across is called the participating site; chemical reactions occur at the combat-ready site. Catalase is found in all cells and protects them from a dangerous crazy chemical called Hydrogen Peroxide. It breaks the hydrogen hydrogen peroxide down to water supply and oxygen T he substratum (hydrogen peroxide) and the catalase molecules are continuously on the move. E precise so often they allow for collide so that the subst invest molecule(s) fits into the enzymes active site. Then the substrate is broken down into the two products The enzyme is not used up in the reaction.

So it buttocks observe its work factors affecting function of enzymes temperature, substrate concentration, pH Temperature and enzymes As the temperature increases, so does the rate of reaction as the enzymes have more cogency. But very racy temperatures denature enzymes.(this means they deform so that substrate molecules cant fit into t! he active site) The enzyme activity in stages increases with temperature until it reaches the optimal temperature which is around 37ºC, or body temperature. Then, as the temperature continues to rise, the rate of reaction falls rapidly, as heat energy denatures the enzyme pH and enzymes Different enzymes work at their best at distinct pH values. For example, enzymes in the stomach have an optimal pH of about 2 because...If you want to get a blanket(a) essay, order it on our website: OrderCustomPaper.com
