The protein cyclophilin is a monomer with a diffusion constant of 1.2 x 10-8 cm2•sec-1, in water at 25°C. Cyclophilin binds the HIV capsid and the resulting complex has a diffusion constant of 7 x 10-9 cm2•sec-1. Determine the typical (rms) distances that cyclophilin alone and the cyclophilin-capsid complex will travel in 10 sec. Does the binding of cyclophilin cause a significant change in the diffusion constant of the HIV capsid?

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

In an oxidation-reduction reaction, oxidation is what happens when a reactant

Which is an example of the practical pursuit of alchemy? a. forming perfect substances. b. transforming base metals. c. developing metalworking techniques. d. linking spiritual characteristics with material substances.
