antifreeze solution. 3. Using the formula molar mass = grams/moles calculate the molecular mass of antifreeze in the 10% solution. 4. Using the equation ΔT = Kf m¸calculate the molality of the 20% antifreeze solution. 5. Use the formula molality = moles solute/kg solvent to find the number of moles in 20% antifreeze solution. 6. Using the formula molar mass = grams/moles calculate the molecular mass of antifreeze in the 20% solution. 7. Average the molar masses you calculated

No DNA fragmentation occurred in the untreated cells. 3.9. Caspase-3 expression in apoptotic cells The molecular effectors that activate a series of protease that leads to programmed cell death by intrinsic and extrinsic pathways are known as caspases. Caspase-3 dependent apoptotic cell death was induced by Pierisin-6 in human cancer cell lines were . The HeLa

[LIVMFAP] - [GAD] [2-8]. The heme is used to oxidize drugs by adding a hydroxyl group to these substances‚ often as a way to rid the body of potentially harmful toxins in order to make them more water-soluble. They do this by inserting one atom of molecular dioxygen into an organic substrate (RH) while the second oxygen atom is reduced to water (RH+02 + 2e- → ROH + H20). CYP catalysis substrate binding to the heme site requires a two-electron transfer with NADH-cytochrome P450 oxidoreductase (CPR) to

Electrophoresis can take a mixture of macromolecules of different molecular weights‚ shapes‚ and various electrical charges to determine all the various compounds in the mixture and allowing for further purification that can aid in details of individual elements of the mixture being studied. Agarose gel electrophoresis is a very important technique used in the field of molecular science. The field of forensics utilizes agarose gel electrophoresis by allowing investigators

According to your results‚ which solute had the highest molecular weight? The solute that had the highest molecular weight was Albumin. Which solute displayed the highest rate of diffusion through the 200 MWCO membrane? The solute that displayed the highest rate of diffusion through the 200 MWCO

My prediction is that Potassium Permanganate KMnO4- purple (molecular mass- 158.03 g/mol) will move further than Methylene blue‚ solid (molecular mass- 319.85 g/mol) since it weighs less. In osmosis is diffusion of H2O across a selectively permeable membrane (dialysis tubing). There is only movement of water‚ not solute‚ across the plasma membrane. Water
