4. Which of the following statements concerning the thermodynamics of biochemical reactions are true? Briefly explain why each statement is true or false. i. Enzymes exploit Le Chatelier's principle to decrease $$?G^{?}\mathrm{xn}$$, making a reaction more favorable. ii. Most enzyme-catalyzed reactions that couple unfavorable reactions with ATP hydrolysis proceed via a different pathway compared to the uncatalyzed reaction. iii. Enzymes lower $$?G^{?}$$ mon by increasing $$K_{eq}$$ of a reaction. iv. Many cellular reactions essential to life are nonspontaneous and require enzymes to couple them with favorable reactions.
