Multiple Choice

In a biochemical reaction,A + B $\to$ C with $In a biochemical reaction,A + B \to C with = 30 kJ/mol.Which of the following reactions might be effectively coupled to this reaction so that it becomes more spontaneous? (I) C + D \to B + E = -40 kJ/mol (II) C + D \to B + E = +40 kJ/mol A) I only B) II only C) I or II D) Neither I nor II can increase spontaneity. E) No coupling is required,as the reaction is already spontaneous.$ = 30 kJ/mol.Which of the following reactions might be effectively coupled to this reaction so that it becomes more spontaneous?
