A)Consider these hypothetical chemical reactions: A⇌B,ΔG=A⇌B,ΔG= 13.5 kJ/molkJ/mol B⇌C,ΔG=B⇌C,ΔG= -27.6 kJ/molkJ/mol C⇌D,ΔG=C⇌D,ΔG= 9.90 kJ/molkJ/mol What is the free energy, ΔGΔGDelta G, for the overall reaction, A⇌DA⇌D? B)Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP. In this way, luciferase can test for the presence of life. The coupled reactions are: luciferin+O2ATP⇌oxyluciferin+light ATP⇌AMP+PPi If the overall ΔGDelta G of the coupled reaction is -9.00 kJ/mol , what is the equilibrium constant, KKK, of the first reactions at 13 ∘C ? The ΔGDelta for the hydrolysis of ATP to AMP is −31.6 kJ/mol. Express your answer numerically.
