If the standard free energy change for the reaction converting A to B is unfavor

Question

If the standard free energy change for the reaction converting A to B is unfavorable, how can this reaction proceed in the forward direction under cellular conditions? Select TWO correct answers.

Question 4 options:

Couple the reaction to an exergonic reaction such as ATP hydrolysis.

The reaction cannot proceed in the forward direction under any circumstances since the standard free energy change is positive.

Decrease the cellular concentration of B until the actual free energy change is now negative.

Decrease the cellular concentrations of A until the actual free energy change is now negative.

There are not two correct answers.
