Question

Look that data set provided by an enzyme reaction. Graph the information and attach your graph. Hypothesis what is being tested with this data set. Identify the independent variable and dependent variable. Conditions (pH 7,25 degrees Celsius)

This is the only info provided on my HW. If you all could please help to the best of your abilities. Thanks!

Answer 1

100 Oxygen volume vs Time 90 80 70 y= 1.462x + 1.890 60 Cumulative oxygen volume (cc) 50 40 30 20 10 0 0 10 20 30 40 50 60 70 Time (seconds)

1. The hypothesis which is being tested in the above question is whether the oxygen consumption changes with time.

2. The independent variable is the variable which can be manipulated by the experimenter, can stand alone and it has a direct effect on dependent variable; while dependent variable is the variable whose variations depend on other variable. In the above question "time" is the independent variable and cumulative oxygen consumption is the dependent variable.

3.The equation obtained after plotting the data in excel is y = 1.462 X + 1.890. This equation is similar to the equation of straight line y = mx + c. Here in this equation m is the slope of the line. Therefore the slope of the line calculated from equation is 1.462.

4. The trendline observed in the graph is linear trendline. A linear trendline is a best-fit straight line which is used with simple linear data sets. It usually shows that the data is increasing as can be observed from the graph, the volume of oxygen is increasing with increase in time at a steady rate.
