"The chains of several cell membrane - bound proteins are known to wind back and forth through the cell membrane, such that some parts of the protein structure are extracellular, some parts are intracellular, and some parts lie within the cell membrane. How might the primary structure of such a protein help in distinguishing the portions of the protein embedded within the cell membrane from those positioned intracellularly or extracellularly?
Determine the pressure inside a container of a gas connected to an open-end manometer filled with CCl4, has the density = 1.594 g/cm3,
A rectangular beam made using concrete with f'c = 6000 psi and steel with fy=60000 psi has a width b= 20 in. The concrete modulus of rupture fr=530 psi. The elastic moduli of the concrete and steel are, respectively,
The insecticide DDT has a half-life in the human body of about 7 years. That is, in 7 years its concentration.( Although DDT is no longer in use in the United States).
H2C2O4(aq), Ka1 = 6.5 x 10-2 and Ka2 = 6.1 x 10-5. Don't forget that Kw = 1 x 10-14. Then Determine K for the reaction
Compute the moment of inertia of the molecule in kg m 2 . And also determine the greatest wavelength of the radiation that can excite the molecule into rotation.
The mass of an Argon atom is more than that of a Helium atom. Does that mean that because of Argon has larger mass, it exerts a higher pressure on the walls of container than Helium at the same volume, molar density and temperature? Give explanati..
Equilibrium between the composition of Hydrogen sulphide in the gaseous and liquid phases can be represented as Yn=48.3Xn.
Provide the newman projections across the C 2 -C 3 bonds for the major conformers after Drawing the zig-zag structures of all the isomers of 2,3-diaminopentane.
