At equilibrium, the concentration of glucose 1-phosphate is 4.5x10 M and that of glucose 6-phosphate is 86x10: M. Calculate the ΔG, for this reaction at 25 °C. 14) 3 points) If the mass action ratio, Q, for a reaction under cellular conditions is larger than the equilibrium constant, K then: A) the reaction will be at equilibrium B) the reaction will go backward and be endergonic C) the reaction will go backward and be exergonic. D) the reaction will go forward and be endergonic E) the reaction will go forward and be exergonic 15) (2 points) The structures of glucose and fructose are shown. Glucose is an whereas fructose is a A) chair/boat B) aldose ketose C) ketose/hexose D) none of the above. CHJON 16) (2 points) The structu Glucose(B 1-3 glucose. re to the right corresponds to a A) False B) True To Do
Please show me your brilliant work !

Answer 1

14. Option C, since Q> K, backward reaction favors with absorption of energy.. Hence endoergic.

15.Option B, since Glucose has aldehyde functional group, hence aldose while fructose has ketone hence ketose

16. Option B, true since it is beta glycosidic bond.
