Working on a pre-lab, some of the directions for drawing graphs is that the "x-axis" is for the non-variables, and the "y-axis" is for the variables (what you have measured).
Now, the first thing I have to do is to make a standard curve for "Glucose concentration" and "Absorbtion".
The next step is to measure the "Enzyme activity" and use the standard curve done to deternmine the amount of glucose since I will be having the "Absorbance" values in the "Enzyme activity" process.
Finally, we are asked to plot a graph that shows the glucose production against time.
Based on that, what (glucose production, time) goes where (x-axis, y-axis)?
