Enzyme lab

Determining Properties of an Enzyme Purpose: Enzymes serve as proteins that influence the tarradiddle of a answer. Enzymes are long chains of amino acids with interlocking shapes. There a variety of enzymes, all(prenominal) with their own righteousness and job. The progressive site on an enzyme is specific to a single substrate, which house activate the energy in the enzyme. Without enzymes normal metabolic reactions would be sluggish. The purpose of this lab was to measure the extent of enzyme reaction on given substrates by means of color change. The tack of temperature and pH volition be testinged and their influence on the enzyme recorded. If the environment is cold, past enzymes go out not activate and if pH is game, then enzymes will not activate. This I believe because at low temperatures reactions pitch to slow down and at high pH allthing will denature. Techniques: Enzyme activity was determined in sevensome test tubes to each one with a distinguis hable combination of buffers, H202, extract, and dye. sort tubes were placed in a mass spectrometer and their absorbance recorded. Absorbance was recorded at cardinal second intervals for two full minutes. A temperature effect on enzymes was measurable by exposing test tubes to four different temperature environments. (4C, manner temperature, 32C, and 48C).Seven test tubes were assembled exactly the same as the sample before.

again the test tubes were placed in a spectrometer and their absorbance was measured at intervals of xx seconds for two minutes. The effect of pH on an enzyme was tested in nine test tu bes, each with a different combination of, b! uffer pH, H202, extract, and dye. Again the test tubes were placed in a spectrometer and their absorbance recorded every twenty seconds for a full two minutes.
