What value of [S], as a fraction of KM, is required to obtain 80% of Vmax? (Hint: use the MM equation, and algebra.) Express your answer as the fraction/multiple of KM needed, for example, if your answer is 2.75 times KM, then enter "2.75" or if your answer is 1/2 times KM, then enter "1/2" or "5" Don't include "x" or "times" just the number.

A friend breeds giant racing Rhosgobel rabbits. She is seeking your advice on how to breed faster rabbits. As per your request, she compared the mid-parent and mid-offspring running speeds. Look at the graph to the below, which of the following statements provides accurate information to your friend. 16 y = 0.0453x + 8.3165 R2 = 0.0028 14 12 10 10 15 20 Midoffspring running speed (m/s) O a. The slower rabbits will produce faster offspring than the faster rabbits in the current generation. O b.If your friend selectively breeds her fastest rabbits, you expect the next generation to be significantly faster. OC. The best way to increase running speed in the next generation would be to alter the environment, maybe increasing nutrient density of the food. O d. There is a higher degree of heritability in other populations of Rhosgobel rabbits. Midparent running speed (s/w)
Use MS Excel to plot and determine the terms being asked: Please insert the excel file, thank you For each V (mmol/min), determine the value of [S] (mM) if Vmax = 5 mmol/min. Show your calculations. Using MS Excel, plot [S] (mM) versus V (mmol/min). Draw a line corresponding to the given Vmax parallel the x-axis and extend your plotted line to show its approach to Vmax. Provide your final plot [S] (mM) V (mmol/min) 10 1.2 1.7 2.1 2.2 2.5 Determine the values of Km and Vmax for the decarboxylation of β-keto acid given the following data.
