Enzyme lab

Determining Properties of an Enzyme Purpose: Enzymes serve as proteins that influence the broadsheet of a answer. Enzymes are long chains of amino acids with meshwork shapes. There a variety of enzymes, all(prenominal) with their own righteousness and job. The alive(p) site on an enzyme is specific to a single substrate, which advise 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 go out be testinged and their influence on the enzyme recorded. If the environment is cold, consequently enzymes allow for not activate and if pH is game, then enzymes will not activate. This I believe because at low temperatures reactions go to slow down and at high pH allthing will denature. Techniques: Enzyme activity was determined in sevensome test tubes for each one with a distinguis hable combination of buffers, H202, extract, and dye. sort tubes were place in a mass spectrometer and their absorbance recorded. Absorbance was recorded at xx dollar bill second intervals for two full minutes. A temperature effect on enzymes was mensural by exposing test tubes to four different temperature environments. (4C, live temperature, 32C, and 48C).Seven test tubes were assembled exactly the same as the sample before.

over again the test tubes were placed in a spectrometer and their absorbance was measured at intervals of twenty seconds for two minutes. The effect of pH on an enzyme was tested in nine test tub es, each with a different combination of, bu! ffer 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.
