Question

What is represented in the following equation?

\(M_r=\frac{RTS}{D(1-Vρ)}\)

(a) Svedberg equation

(b) Miachelis Menten equation

(c) Arrhenius equation

(d) Turn over number

This question was posed to me by my college professor while I was bunking the class.

Question is taken from Determination of Molecular Weight of Enzymes in portion Enzyme Extraction and Purification of Enzyme Technology

Answer 1

Right answer is (a) Svedberg equation

Explanation: The equation, \(M_r=\frac{RTS}{D(1-Vƍ)}\) represents the Svedberg equation which is used in determination of molecular weight by ultracentrifugation. In the above equation,

Mr = Molecular weight, R = Universal gas constant, S = Svedberg constant, D = Diffusion constant, V = partial specific volume of the molecule, ƍ = density.
