Reading in blood glucose meter is 385 mg/dL
= 385 × ( 10-3 g/10-1 L)
= 3.85 g/L
Now molecular weight of glucose=180
So no of moles of glucose per litre = (3.85/180)
=0.0214
So concentration of glucose = 0.0214 M
= 0.0214 × 103 mM
= 21.4 mM
2. As the reaction has occured over 30 minutes so rate of reaction
= Change in concentration/ time
= (21.4/30)mM/min
=0.7133 mM/min.
LINEWEAVER-BURK plot 1. You perform the hydrolysis reaction as required in the lab experiment, and the...
You perform a series of enzyme activity assays and then graph the data using a Lineweaver-Burk plot. You determine the X-intercept is at -0.02 mM-1 and the Y-intercept is at 5.0 (mM/sec)-1. Calculate the Vmax and Km for this enzyme. A. Vmax = 0.20 mM/sec; Km = 50.0 mM B. Vmax = 0.20 mM/sec; Km = ‒50.0 mM C. Vmax = 5.0 mM/sec; Km = 0.02 mM D. Vmax = 5.0 mM/sec; Km = ‒0.02 mM
Please help me with these two problems. I will rate the
answers.
1. The HIV-1 protease, an important enzyme in the life cycle of the human immunodeficiency virus-1 (HIV-1), is a good drug target for the treatment of HIV and AIDS. A protein produced by the virus, p6*, is an HIV-1 protease inhibitor. The activity of the HIV-1 protease was measured in the presence and absence of p6* using an assay involving an artificial substrate, as shown below. NH Lys...
(I need help with part C, Drawing the expected Michaelis-Menten plot; Do NOT draw the Lineweaver-Burk plot. thanks!) 1. Michaelis-Menten kinetics- use the M-M equation to answer the following: a. An enzyme (5 µM) has a Vmax of 450 mM/min. What is kcat? b. When the substrate concentration is 50 mM, the initial velocity (V0) was measured to be 375 mM/min. Under the conditions described above, calculate the KM. c. Draw the expected Michaelis-Menten plot (label your axes and include...
how do you make a lineweaver-burk plot where the trend line
extends backwards? is there a way of figuring out how far back it
should extend based of your data ? As well, how do you plot two
sets of data on one graph ? Thank you! (idk if you need to see my
data-> attached below)
