Investigation in to the factors that affects the rate of fermentation of GlucoseAimTo investigate the factors that affects the rate of fermentation ofGlucose.Background knowledge.ENZYMES excitement is a form of an anaerobic respiration where by glucose ispartially broken down so only a small pith of energy is released.The barm cells use the enzymes, ZYMASE to break down sugars unable toobtain.GLUCOSE CARBON DIOXIDE + ETHANOL(+ENERGY) C6 H12 O6 6CO2 + C2H5OH (210KJ)Enzymes prevail several properties.1) Specific actions-Zyamse in yeast lap ups on glucose.2) A small amount is required as the enzyme is used again and again as it is uncharged at the end therefore one of my variables could be varying the quantity of yeast.3) severally enzyme has its own specific temperature at which it works best. This is the factor at which I am going to investigate zymase in yeast. There are some enzymes which work best in cold eg. Fridge. And others that can stand considerably high tempe ratures.All enzymes are proteins as they are made by living cells. and thenhigh temperatures cause protein to become DENATURED, destroyed,exaclty the same way as the cooked white of an egg cannot be changedback to its runny state. When proetin of an ezyme is denatured it nolonger functions as a catalyst.COLLISION THEORYRate of reaction simply depends on how hard and often the reactingparticles collide with each other.The basic idea is that particles have to collide with each other inorder to react.MORE COLLISIONS INCREASE THE RATE OF REACTION.1) Temperature increases the number of smashs.2) Concentration (or pressure) in creases the number of collisions.3) Sizes of solid particles (or surface area) incr... ...ature of 40-50, therefore themolecules reacted faster and harder, collision theory, which starts togive off a gas, CO2. The glucose changes into a gas, Kinetic theory.My graph of my results shows that the Carbon Dioxide produced did notreact as fast as the enzyme which is wo rking as a catalyst has eitherstopped or died. My prediction has been a success.GLUCOSE CARBON DIOXIDE + ETHANOL(+ENERGY) C6 H12 O6 6CO2 + C2H5OH (210KJ)EvaluationI really enjoyed doing this experiment, which is unusual I did myresearch well. Using divers(prenominal) types of materials, Internet, Library,Revision books.I think it would have been better if I had of done each temperaturethree times so that I could have found an average. It would have beenabit more fairer and bit more accurate.I also missed the prototypic week so it was a little bit confusing at firstbut it turned out okay.
