Accepted Answer

the reactants will be favored

Question 2

Reactions that have positive standard free energy changes (ΔGo> 0) can be made to occur in cells by

Accepted Answer

all of the above

Question 3

The unfolding of regular secondary structure causes

Accepted Answer

large increase in the entropy of the protein

Question 4

The Standard Gibb's free energy, ΔG°, is

Accepted Answer

the energy required to convert one mole of reactants to one mole of products

Question 5

During the unfolding reaction of a helix, breakage of each hydrogen bond requires about 2kJ/mol. This implies hydrogen bonds are

Accepted Answer

slightly stronger in proteins than in water
