In a Temperature-Jump Experiment to Investigate the Kinetics of Protein

question 14

Multiple Choice

In a temperature-jump experiment to investigate the kinetics of protein folding, the relaxation time following perturbation of the equilibrated system was measured to be 240 ns. Both the forward and backward transformations were found to be first order, with the rate constant for the forward transformation known to be 1.1  10⁶ s^-1. Determine the rate constant for the backward transformation.

• A) 2.2  10^-18 s^-1
• B) 4.6  10¹² s^-1
• C) 4.2  10⁶ s^-1
• D) 3.1  10⁶ s^-1
