Analogously to our titration exercise, we will use the M-M equation as our model for the enzyme reaction system. I got my macbook in and the software is: Go to Insert – Chart 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. 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. Posted on Apr 6, 6:

Then change the value of K m to 0. 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. How was this data derived? The chart shows the initial velocity of the substrates with and without inhibition. Apr 6, 6: Go to Insert – Chart Apr 4, 9:

I am not sure how to go from a basic scatter plot chart to a double reciprocal plot. The Ogden professor’s interpretation of “Lineweaver Burk plot” would appear to be different from what you are asking for.

Make a new chart of this data, labeling appropriately etc. 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. Duplicate and copy your spread sheet columns capture the columns with the mouse, then click on a cell, say F, and hit enter:.

Go to Insert – Chart Apr 4, 6: Next plot your results. How was this data derived?

Reply Helpful Thread reply – more options Link to this Post. The green anb blue trend lines on your chart appear to be related to the data in the unlabelled columns E, F and G of your table. Apr 4, 9: What labels should sxcel on each column?

Also their example was different from the one I need. How accurate and effective do you think this plot bkrk for finding values from real data? So something like this, then? When trend lines and the trend line equations are added, it resembles the one in your initial post.

Ignoring the known values for Km and Vmax, find them graphically from your plots. I got my macbook in and the software is: 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.

Zeroes are added manually in G2 and F3 to mak 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.

To start the conversation again, simply ask a new question.

Now go back and add a line to the plot excle going under ChartAdd Trendline. Set up your spread sheet as in the figure:. For this exercise we need to set up columns for the various parameters in the Michaelis-Menten equation. The same kinds of techniques we used before for the titration curves will be used. View answer in context.

I checked the site. The chart shows the initial velocity of the substrates with and without inhibition.

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. It didn’t show how to make a correct graph using numbers. Question marked as Solved User profile for user: Posted on Apr 4, 4: The three unlabelled columns are linneweaver reciprocal values of the input data in order. Posted on Apr 6, 6: Creating a similar chart in Numbers should be fairly straightforward using the Excel instructions.

What are its problems? Then change the value of K m to 0. Next fill the substrate column with concentrations from 0 – 5 Go to Edit – Fill – Serieswhen the dialog box comes up click on the radio button for columns under Series inthen set the step value to 0.

Apr buro, 6: 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.

Analogously to our titration exercise, we will use the M-M equation as our model for the enzyme reaction system. In the dialog boxes choose linear, then double-click on the line and under options choose display equation and r-squared The data from your table is in rows of columns A, B and C.

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