Introduction: Enzymes are a kind of protein that catalyze reactions by bonding to specifically shaped active sites thus lowering the energy reaction level which in turn speeds up the reaction. ... We also hypothesized that because enzyme and substrate concentrations in a reaction are proportional to each other, the reaction will occur at a speed proportionate to the amount of enzyme/substrate present. ... As soon as the catechol was added, readings of absorbance were taken on the spectrophotometer. Readings were taken at 0 minutes and then every 2 minutes up until 10 minutes. ... F...

Using absorbance readings, reaction rate and optimal levels can be concluded. ... After the initial reading, one ml of α-amylase was dropped and stirred into the to 70 ml solution. ... Since enzymes cannot cause inefficient reactions to occur, I can be sure that the reaction will either speed up or have no reaction with the enzyme. ... Beyond that temperature, however, the speed of the enzymatic reaction drops sharply. ... After the initial reading, one ml of α-amylase was dropped and stirred into the to 70 ml solution. ...

Enzymes are biological catalysts, meaning they speed up a reaction. ... The final random error that occurred had to do with temperature readings. ... If the thermometer used gave inaccurate readings, then it could change the outcome of the experiment. ...
