How Substrate Concentration Affects Enzyme Activity Lab Report

How Subst lay out Concentration Affects Enzyme Activity The purpose of the essay was to observe how substrate tautness affects enzyme activity. My supposition is that the much substrate concentration thither is, the more than p gatuct it will roll; this is until it reaches the point of saturation, after(prenominal) that, the enzyme will be unable to produce at a faster rate. To prove this, twenty atomic calculate 23 mental tests were made, five trials for five different concentrations of substrate with the resembling amount of enzyme, recording the rate of out fix up for each trial. For this experiment, atomic number 1 peroxide was used as the substrate, and catalase as the enzyme. Each trial was five milliliters of substrate, adding ten drops of enzyme, delay 30 secs, shaking it twice, and gushing(a) it into a bottle where the atomic number 8 (as the product) would be recorded. The outcome of this experiment turned out as follows: the total rate of molecular ty pe O produced for two per centum heat content peroxide was 0.05 percent of molecular oxygen per second; for four, six, eightsome and ten percent the average rate was 0.06, 0.07, 0.08, 0.10 percent of molecular oxygen per second respectively. The results are close to being linear, with an r² value of 0.9888.

One could say the outcome is safe because it shows how by having more concentration of substrate the molecular oxygen production is increased. Alas, the investigative question cannot be fully answered; this is because more tests could hurt been made with higher concentration of substrate, showing a more accurate representation of what might happen, and, possibly, showing when in crease the concentration the reaction rate w! ould no longer increase, proving the hypothesis right. In addition, looking at the graph it is noticeable how the misplay disallow are ample; the reason for vast misplay bars could be caused by interrupting the experimental process by go the table while the experiment was ongoing, inaccurate measuring rod of catalase enzyme, or cleanliness.
