Presume that each PTK receptor bound to a growth factor converts 95 molecules of Ras protein into GTP forms in 1 second as well as each GTP-bound Ras protein activates 12 Raf kinases in 1 second. Compute how many active Raf kinases will be produced in three seconds after activation of PTK in the absence GAP. Presume that Ras hydrolyses GTP with the rate of 2 molecules/min in the absence of GAP
Write a line angle formula of each constitutional isomer of dimethylcyclohexane. Write the IUPAC name of each isomer.
Calculate the molarity of of each ion present in the solution. Please walk me through the steps I'm trying to help my daughter with her chem. homework and I don't know any chem.
If you prepared a solution by adding equal numbers of moles sodium sulfite (Na2SO3) and sodium hydrogen sulfite (NaHSO3) to 50 mL water, what would be the pH of the solution?
draw and name all monochlorinated products of 2,2,3-trimethylpentane. Predict the percentage of each product. Would you obtain the same major product if you were to use bromine in place of chlorine
Determine the mass of sodium formate that must be dissolved in 450.0cm3 of a 1.2M solution of formic acid to get a buffer solution with pH = 3.70.
At 9.°C and 1.40 atm pressure, a sample of helium gas occupies a volume of 5.10 L. The sample is compressed and heated to 60.°C. Calculate the final pressure of the sample, if the final volume is 3.64 L.
If a 1.443 gram sample of metal is reacted with excess oxygen to yield 1.683 grams of the oxide M3O2 M being the metal Compute the atomic mass of the element M and identify the metal.
What mass of LP gas is necessary to heat 1.3 of water from room temperature (25.0 ) to boiling (100.0 )? Assume that during heating, 16% of the heat emitted by the LP gas combustion goes to heat the water.
The radioactive decay of a certain sample produced 936 disintegrations per minute. Exactly 3.00 days later, the rate of decay was found to be 511 disintegrations per minute. Calculate the half-life, in days, for the decay of this sample.
