K'_eq and Q, the mass-action ratio, can determine whether a metabolic reaction is far from equilibrium. Fructose 6-phosphate + ATP Fructose 1, 6-bis phosphate + ADP Calculate K'_eq for this reaction at T = 25.0 degree C. delta G degree = -14.2 kJ/mol Calculate the mass-action ratio, Q, from the approximate physiological concentrations for rat heart tissue shown at the right. Select the true statements about the PFK-1 reaction. A. In heart tissue, the PFK-1 reaction will be driven toward product formation. B. Under standard conditions, the PFK-1 reaction reaches equilibrium when the concentrations of all products and reactants are equal. C. The PFK-1 reaction in heart tissue does not reach equilibrium. D. In heart tissue, the PFK-1 products are more abundant than reactants.
