1.
During the unfolding reaction of a helix, breakage of each hydrogen bond requires about 2kJ/mol. This implies hydrogen bonds are
much stronger in proteins than in water
not reformed with water
slightly weaker in proteins than in water
slightly stronger in proteins than in water

3.
Reactions that have positive standard free energy changes (ΔGo> 0) can be made to occur in cells by
coupling them with exergonic reactions via a common intermediate
manipulating the concentrations of products and reactants such that G/<0
coupling them to the hydrolysis of ATP
all of the above
Answer: Option
Explanation:

4.
The Standard Gibb's free energy, ΔG°, is
the residual energy present in the reactants at equilibrium
the residual energy present in the products at equilibrium
the difference in the residual energy of reactants and products at equilibrium
the energy required to convert one mole of reactants to one mole of products
Answer: Option
Explanation:
No answer description is available. Let's discuss.
5.
If the Standard Gibb's free energy, ΔG°, for a reaction is positive then
the products will be favored
