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 1. luciferin + O₂ 2. ATP oxyluciferin + light AMP+PP AG-31.6 kJ/mol If the overall AG of the coupled reaction is -5.20 kJ/mol, what is the equilibrium constant, K, of the first reaction at 18 °C?

![Part C
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
1. luciferin + O₂ oxyluciferin + light
2. ATP
=AMP + PP₁
AG = -31.6 kJ/mol
If the overall AG of the coupled reaction is -5.20 kJ/mol, what is the equilibrium constant, K, of the first reaction at 18 °C?
Express your answer numerically.
