Equations: Stokes-Einstein Equation: kB = Boltzmann constant (1.38x10-23 J Kº) T = Absolute temperature η = viscosity of the medium (0.001 for water in SI units) r = radius of the sphere n= “dimensionality” (1D, 2D or 3D) Critical Concentration: Michaelis-Menten Equation: Shows saturation at high substrate concentrations Vmax – rate at saturation for a given enzyme concentration in moles per unit time

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
