Reply Helpful Thread reply – more options Link to this Post. Now go back and add a line to the plot by going under Chart , Add Trendline. Next fill the substrate column with concentrations from 0 – 5 Go to Edit – Fill – Series , when the dialog box comes up click on the radio button for columns under Series in , then set the step value to 0. Can you provide a more detailed description of a Lineweaver Burk plot, and of the data that is plotted compared with the data that has been measured, and is recorded on your data table. It didn’t show how to make a correct graph using numbers. The formulas for converting the data pairs are simple reciprocals, and the chart itself is a scatter plot with a ‘best fit’ linear trend line added.

Analogously to our titration exercise, we will use the M-M equation as our model for the enzyme reaction system. Next plot your results. Posted on Apr 6, 6: Also their example was different from the one I need. It didn’t show how to make a correct graph using numbers. Apr 4, 6: Apr 6, 6:

I am not sure how to go from a basic scatter plot chart to a double reciprocal plot.

Apr 4, 9: The Ogden professor’s interpretation of “Lineweaver Burk plot” would appear to be different from what you are asking for.

I am trying to make a double reciprocal plot from my enzyme data. The same kinds of techniques we used before for the titration curves will be used. The formulas for converting the data pairs are simple reciprocals, and the chart itself is a scatter plot with a ‘best fit’ linear trend line added.

Set up your spread sheet as in the figure:. What are its problems? How was this data derived?

This is done using the constant values in the equations for each slope, shown at top left of the chart, in formulas in E2 and E3.

I got my macbook in and the software is: Duplicate and copy your spread sheet columns capture the columns with the mouse, then click on a cell, say F, and hit enter:. Reply Helpful Thread reply – more options Link to this Post.

This is converted to the reciprocal values in rows of columns E, F and G respectively, header labels are added in row 1 a header rowand cells E4-G7 are selected and a scatte chart created.

ln Next fill the substrate column with concentrations from 0 – 5 Go to Edit – Fill – Serieswhen the p,ot box comes up click on the radio button for columns under Series inthen set the step value to 0.

Question marked as Solved User profile for user: The chart shows the initial velocity of the substrates with and without inhibition. Posted on Apr 4, 4: View answer in context.

Ask a question Reset. How do these values compare to each other and to the “real” values.

Apr 4, 8: The data from your table is in rows of columns A, B and C. Can you provide a more detailed description of a Lineweaver Burk plot, and of the data that is plotted compared with the data that has been measured, and is recorded on your data table.

For this exercise we need to set up columns for the various parameters in the Michaelis-Menten equation. plott

So something like this, then? Analogously to our titration exercise, we will use the M-M equation as our model for the enzyme reaction system. Ignoring the lineweavr-burk values for Km and Vmax, find them graphically from your plots. Zeroes are added manually in G2 and F3 to specify the Y value where each slope meets the x axis, then the chart is selected again, and the selection rectangle enclosing cells E4-G7 is slid up two rows, then extended down two rows to include cells E2 – G7.

When trend lines and the trend line equations are added, it resembles the one in your initial post. Apr 6, amke What labels should be on each column? Now go back and add a line to the plot by going under ChartAdd Trendline. To start the conversation again, simply ask a new question. Go to Insert – Chart How accurate and effective do you think this mke is for finding values from real data?

It didn’t show how to make a correct graph using numbers. In the dialog boxes choose linear, then double-click on the line and under options choose display equation and r-squared Posted on Apr 6, 6: I checked the site.

The three unlabelled columns are the reciprocal values of the input data in order. Make a new chart of this data, labeling appropriately etc. Apr 4, 6:
