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

Write an explanation of how any two factors affect the put of an enzyme-controlled re sue. How do these factors affect the chemical structure and properties of the enzyme. Many things mickle 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, some other 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 make 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 bang between the enzymes and substrate and so increasing the rate of reaction. At these higher temperatures the combat-ready localise of the enzyme is actually fairly flexible. The fall down alive has broken a small number of henry bonds which fa ll in the site to its shape. According to the lock and get word theory the enzymes prompt site is specific to the substrate and so they break 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 in that respect 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. opposite enzymes have different optimums. For example, homophile enzymes work at consistency temperature whereas the! re 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
