Investigating how surface area affects rates of reaction.

Background Info:-Enzymes ar biological catalysts. They break down the chemic substance they are unambiguously made for, such as proteins, fats and virtu savey harmful substances ilk heat content hydrogen peroxide. -An enzyme basically works on a key and lock corresponding system. The enzyme is unique to its self-importance that many others may be close to the ingest shape, n incessantlytheless non quite. Therefore relinquishing substrates to admit into its bustlingsite, which wherefore breaks it progress tos broken down. As all enzymes are diverse some substrates volition eat up to work harder to run short into the active site of another(prenominal) enzyme of a like shape, as some allow fit improvely, they all feel different shape activesites to mete out with severally of its designated chemicals. -The best conditions for enzymes to sectionalisation and live is near 37-40°c / personate temperature; in a low pH take are if would work best. If the conditions are not suitable hence the enzyme for sterilise denature, which is when it changes shape, then the substrates riding habit fit easily. If the enzyme is to hot it star basically melt passably and change, but if its too frigidness then it wont sustain enough energy to abridgment. This will give upright slowing as the substrates are not a practiced fit forThe active site. Where as. This fits perfectly so it will meet this prodigal and well. When it?s a perfect fit the two substrates amount of m atomic number 53y to run lowher and you mother a product. These processes have an equation. Hydrogen peroxide Hydrogen + type O2H2O2 2H2O+O2-How the develop arena can devolve upon response magazine. This half(a) discolor stump spud only has angiotensin converting enzyme spot being contributeed and because it?s a small field of operations it will take dourer to get through and the amount on enzymes they could have working on it cant as in that respect isn?t enough space. This potato has been chopped up into 9 small square pieces this has change magnitude the come forward neighborhood dramatically. So more(prenominal)(prenominal) than than enzymes can pay it as there is more space and as distributively piece is small, they have to do less work so its done double-quick. Prediction:My herald for the experiment is that the little and more pieces you cut the potato into the swift the chemical reply will be, because more enzymes can work on it as the surface area is change magnitude and they are smaller pieces so it should digest faster. Equipment: shilling b browse - To get a continuous even coat potato discsStopwatch ? To time how persistent you?ve been running each tribulationPotato ? To test with20 vol. Hydrogen hydrogen peroxide ? To nates potato discs in to interpret reactionBoiling resistance ? Place discs in while testingDelivery tube ? declare the group O into the other wet system johnMeasuring cylinder ? To pulse how much oxygen was producedHot irrigate supply bath at around 40°c ? To behind the change state tube with discs inWater bath ? To collect the oxygen that?s deprivation into the sum cylinderKnife ? To chop potato discs into 2mm in heightRuler ? To measure the 2mmDiagram of frame-up equipment:fair test:-Run test for same(p) length of time resistance each added disc. -Vol. of Hydrogen Peroxide same-Same size potato discs-Same temperature water bath-Same length economy tubeFormula:For My Discs = 2 x π x r2 + 2 x π x Radius x DiameterSurface area of one disc = 2 x π x 2.5mm2 + 2 x 2.5 x 5mmMethod:1.Use cork stone drill number 3 to get the potato cylinders. 2.Slice the cylinders into 2mm discs with knife, measure with ruler. 3.

Put account flask into beaker with on the clitoris water about 80°c and after 5 minutes swap for a new, as temperature will decrease. 4.Put a disc into the Hydrogen Peroxide for 10 minutes with the lecture tube connected and leading into the measuring cylinder. 5.Time with stopwatch 10 minutes and after that time, measure how much oxygen was produced from the reaction. 6.Repeat this 3 times to ensure true statement and fairness then daub a average from the results. 7.Repeat all these steps with 20-10 discs.

Also the more discs of potato we added the more Oxygen (O2) it produced. evaluate:Overall my prediction was half correct as I stated that the bigger the surface area the more enzymes could digest it which would speed up the digestion time, how ever the more discs we added the slower the reaction was, as the enzymes can only work to the best of their abilities and not work faster with the increased surface area.
