Question #5. 10 points Shown below is a cartoon representation of the energy landscape of a hypothetical protein with and without the assistance of a chaperone. You'll note differences in various physical aspects of the two funnels. Folding funnel Chaperonin- assisted Spontaneous Enthalpy Entropy Kinetic trap Why does the size of the top of the funnel change in the Chaperone assisted model? Why are the kinetic traps minimized in the Chaperone assisted model? Why does enthalpy not change?
