Enzyme-controlled reaction, factors that affect the chemical structure and properties of the enzyme.

Write an explanation of how any two factors affect the stride of an enzyme-controlled re legal action. How do these factors affect the chemical structure and properties of the enzyme. Many things loafer affect the rate of enzyme activity. The temperature of the enzyme, the pH of the solution, the concentration of the enzyme, substrate and the product. Also, another(prenominal) affector is the number of competitive and non-competitive inhibitors. As I cannot explain them all, I have chosen to explain the meat of temperature and also the depression of inhibitors on enzyme activity. Temperature : As the temperature is increased the kinetic possible action is applied. More energy is read and the molecules move fast. This increases the chance of hit between the enzymes and substrate and so increasing the rate of reaction. At these higher temperatures the combat-ready put of the enzyme is actually fairly flexible. The semen alive has broken a small number of hydro gen bonds which fall in the site to its shape. According to the lock and chance on theory the enzymes dynamical site is specific to the substrate and so they give-up the ghost together. The enzyme but catalases a single reaction. As the site is now flexible, thither is an increased amount of induced fit and so the end product of an enzyme-substrate complex is more likely.

If the temperature is lower, the active site of the enzyme is much little flexible as on that point is the maximum number of bonds present holding it all together. At the optimum temperature shown on the curve, the conditions are perfect for this enzyme to work in. unlike enzymes have different optimums. Fo r example, homophile enzymes work at consi! stency temperature whereas there are thermophilic/ durable enzymes which are optimum at much higher temperatures such(prenominal) as 85C. Once the enzyme-substrate complex has been formed, the energizing energy is lowered... If you unavoidableness to get a full essay, order it on our website: OrderEssay.net
