The Reaction Pyruvate + ATP $\leftrightarrows$ PEP + ADP Is Catalyzed by the Enzyme Pyruvate Kinase

question 7

Essay

The reaction pyruvate + ATP $\leftrightarrows$ PEP + ADP is catalyzed by the enzyme pyruvate kinase.The $\Delta$ G°ꞌ for this reaction is 31.4 kJ/mol.Use this information to answer the following questions.
a.Does this reaction move forward (from left to right)or backward under standard state conditions? Explain you answer in one sentence.
b.Calculate the K_eq for this reaction at 25°C.
c.After the reaction has reached equilibrium at 25°C [ATP] = 5 mM,[ADP] = 0.5 mM,[pyruvate] = 0.2 mM.Calculate the concentration PEP.
