In the Reaction a + B <-> C + D $\Delta$

question 79

Multiple Choice

In the reaction A + B <-> C + D, how might the reaction take place in the cell if the $\Delta$ G is very positive?

• A)The reaction would probably take place by coupling it to a reaction with a larger -\(\Delta\)G so that when the \(\Delta\)G values are added up the sum is negative.
• B)The reaction would probably take place by coupling it to a reaction with a smaller -\(\Delta\)G so that when the \(\Delta\)G values are added up the sum is positive.
• C)The reaction would probably take place by coupling it to a reaction with a larger \(\Delta\)G so that when the \(\Delta\)G values are added up the sum is positive.
• D)The reaction would probably take place by coupling it to a reaction with the same positive \(\Delta\)G so that when the \(\Delta\)G values are added up the energy levels balance.
