Cholera toxin (CT) is a protein composed of 6 separate polypeptide chains: one A subunit and five identical B subunits. The B subunits form a pentameric (=five member) ring by sequentially associating through multiple non-covalent interactions with each other. Under physiological conditions, the association is spontaneous and rather strong. What do you expect the free energy change of the assembly process to be?
A. ΔG < 0
B. ΔG > 0
C. ΔG = 0
D. insufficient information to determine.
if it is spontaneous than the change in free energy is negative. so A
