Please do the following work and be prepared to submit it in person by the due date. $(20$ pts total$)1.$ Complete the first table in the lab manual by computing the "Actual Substrate Concentration", recalling that in the solution you created, you mixed a constant amount of enzyme solution into each of the $8$ test tubes you prepared with varying amounts of substrate$\mathrm{.}2.$ With the data you have in the third table, plot the standard curve using a spreadsheet program $($like Excel$),$ and do a linear regression to obtain the equation of the best$-$fit line$\mathrm{.}3.$ Use the linear equation you obtained in procedure #$2$ above to convert all the Absorbance values in the second table in the lab manual into amounts of product$\mathrm{.}4.$ Lastly, plot each of the progress curves from the amounts of product you got in procedure #$3$ above. As a reminder, the progress curve's x$-$axis is time, and the y$-$axis is the amount of product. Remember also that there are eight different experiments $($each with a different substrate concentration$),$ so you must plot a total of eight progress curves. $($You could choose to plot these eight progress curves in one graph, or in eight separate graphsit is up to you.$)$
