Thermodynamics and Free Energy Questions

• If the Standard Gibb's free energy, ΔG°, for a reaction is positive then
• Reactions that have positive standard free energy changes (ΔGo> 0) can be made to occur in cells by
• The unfolding of regular secondary structure causes
• The Standard Gibb's free energy, ΔG°, is
• During the unfolding reaction of a helix, breakage of each hydrogen bond requires about 2kJ/mol. This implies hydrogen bonds are
• If the enthalpy change for a reaction is zero, ΔG° is equal to
