Investigating Enzymes Coursework

Investigating Enzymes Aim: To investigate how temperature affects the send of chemical reaction in enzymes. Introduction: We are investigating how temperature affects the arrange of reaction in enzymes. Different reactions can draw at different rates. Reactions that reckoning into slowly have a low rate of reaction. Reactions that rule quickly have a high rate of reaction. chemical reactions can only happen if reactant particles collide with sufficient energy. The much than frequently particles collide, and the greater the proportion of hits with enough energy, the greater the rate of reaction. Temperature affects the rate of reaction because particles can only react when they collide. If you hotness a substance, the particles move faster and so collide more(prenominal) frequently. That will speed up the rate of reaction. Concentration in like manner affects the rate of reaction because if the concentration is higher, the chances of collision are grea ter. both(prenominal) other factor that can affect the rate of reaction is airfoil area; this is because increasing the surface area of the steady increases the chances of collision taking place. Apparatus list: 10ml syringe for draw because it is more right for our measurements. 5ml syringe for proteinase because it is more accurate as we used a smaller amount of protease than milk.

take out we had more milk than we precisely needed, effective in causa we had to repeat the experiment more than 3 times and/or made any mistakes. Protease enough for multiple tests and in case of any mistakes. Wate! r lavatory to heat up the milk and protease before unite them. Ice cubes to chill out down the milk and protease. case shot foil to insulate the kind and keep the temperature consistent. Test tubes x3 unmatchable for milk, one for protease and one for the mixture. We found it easier to change the temperature independently and keep the mixture in one tube as it makes our results more accurate.
