I. Introduction/Background/Purpose/Hypothesis: BACKROUND: An enzyme is a protein that controls the chemical reactions that take place in the body. Enzymes help by catalyzing (speeding up) the reaction and intern lowering the activation energy required for the reaction to occur. Molecules called substrates bind with enzymes during reactions. However each enzyme has a very specific purpose. The shape of the active site on the enzyme’s outer layer determines that purpose, along with …showed first 75 words of 1148 total…

After the averages were collected then standard deviations were determined according to the formula found in the lab manual page 1-7. The averages were put into graph form and examined. By close evaluation of the data collected, the original hypothesis was proven to be true. Bibliography LaFave,Carol.
