question 80

Multiple Choice

In a biochemical reaction, A + B $\rightarrow$ C with $\Delta$ G _rxn = 30 kJ/mol.Which of the following reactions might be effectively coupled to this reaction so that it becomes more spontaneous?
I.C + D $\rightarrow$ B + E $\quad$ $\Delta$ G11eed8bc_7201_40f9_a0ba_bb7e9d9ada91_TB6562_11 _rxn = -40 kJ/mol
II) C+ D $\rightarrow$ B + E $\quad$ $\Delta$ G 11eed8bc_7201_40f9_a0ba_bb7e9d9ada91_TB6562_11 _rxn = +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.
