Quantitative data are numerical values obtained from counting or measurements. Since absorbance is used as a measure of reaction, the greatest rate of conversion of catechol and oxygen to benzoquinone was seen in Tube 2.

Unless you actually made a mistake following the methods of the experiment, and could not go back and correct it, do not make up such errors to explain the variances you observe.

This is due to the fact that the acidic environment is harmful to the enzyme, and denatures it. Science of Life. One example of this is the affects harsh environmental factors have on enzymes. The title should be descriptive e. The settling reduced the surface area of the substrate that could be attacked by the enzyme. Unless you actually made a mistake following the methods of the experiment, and could not go back and correct it, do not make up such errors to explain the variances you observe. You will want to fully discuss and interpret the information. Pay particular attention to the precision of the measuring instrument you are using. Examination bodies require investigations to be carried out under given topics. Italicized words are links to explanations of why that particular part of the introduction is important and what makes the sentences appropriate or in need of improvement. We observed that Tube 2, which had the highest concentration of enzyme, catecholase, also had the highest absorbance level. When working with large numbers of objects, error may be minimized by using a tally chart. The high ratio of enzyme to substrate caused the absorbance to grow rapidly and then level off see Figure 1. Usually provided by your teacher or instructor.

DATE: Write the date on which the experiment was conducted, or on which it was started if observations are made over a number of days. Catecholase, an enzyme found in potatoes, converts catechol to benzoquinone in the presence of oxygen.

The discussion section should definitely have a statement of your expected findings Pechenik, The title should be to the point, descriptive, accurate, and concise ten words or less.

That includes any books, articles, lab manuals, etc. There should be an explanation of unexpected results Pechenik,
