The correct answers are given below

Explanation:

Cells can manipulate the free energy of reaction by changing the concentration of product and reactant. This is because the free energy of a chemical or biochemical reaction depends on equilibrium constant of that reaction and the equilibrium constant inturn depends on the concentration of both reactant and product.

Using enzymes A lowering the activation barrier of a reaction. Enzymes act as biological catalyst by lowering the energy barrier called activation energy of a reaction but does not have any effect on the reaction"s equilibrium.
