- 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.Discuss the relationship of Lineweaver-Burke and Michaelis Menten equations. What are the importance of the double reciprocal plot, Michaelis constant, and Vmax?Pls help me with the given question and explain your correct answer, thank you A group of absent-minded scientists has two numbers (25.4 and 2.54) written on a scrap of paper.
