b. inhibition of the cAMP cascade
c. decreased phosphorylation of enzymes by protein kinase A

what is the final volume of a 400.0 ml gas sample that is subjected to a temperature change from 22.0 degrees C to 30.0 degrees C and a pressure change from 760 mm Hg to 360 mm Hg
The sample requires 48.24 mL of 0.08893 mol/L Na2S2O3 to reach the equivalence point. Assuming that the Au3+ and Li+ ions are unreactive during titration, determine the ass percent of LiClO sample.
What mass of this substance must evaporate in order to freeze 160 g of water initially at 21 0C? (The heat of fusion of water is 334 {J/g}; the specific heat of water is 4.18 {J/g c.K}.)
A buffer is 0.282 M C6H5COOH (aq) and 0.282 M NA(C6H5COO)(aq). Calculate the pH after the addition of 0.150 moles of nitric acid to 1.0 L of the buffer.
The best means of personal protection from radiation for emergency responders is the implementation of three basic principles: time, distance and shielding. Please show your work when answering the following questions:
Calculate the pH for 5 x 10-10 M HClO4. Please show work. The answer should come out to pH7 when auto-ionization of water is factored
Discuss the differences observed in the IR and NMR spectra of 3-nitrophthal-hydrazide and luminol that are consistent with reduction of the nitro function to an amino group in this experiment.
In a test tube, 10 mL of 0.100 M KI and 10 mL of 0.100 M Na2CO3 are mixed. Next, 0.10 M lead nitrate is added drop wise. What will be the concentration of CO3 2- when PbI2 first starts to precipitate? Ksp (PbCO3) = 1.5 x 10^-13 Ksp (PbI2) = 8.7 x 1..
How many neutrons and protons are contained in the nucleus of this isotope?
What is the concentration of [Cr2O7 ^-2] in the first dilution add that is made by adding 1.00 mL of DI water to 5.00 mL of the stock potassium dichromate solution?
Calculate the resulting pH if 400 mL of 0.50M HCl is mixed with 300 mL of 0.080 M NaOH.
the partial pressure of oxygen in air at sea level is 0.21 atm. using the data in table 13.2, together with henry's law, calculate the molar concentration of oxygen, in the surface water of a mountain lake saturated with air at 20 degrees celcius ..
