State firefly luciferase is the enzyme that allows fireflies

Reference no: EM13208172

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+lightAMP+PPi

If the overall ?G of the coupled reaction is -6.10kJ/mol , what is the equilibrium constant, K, of the first reactions at 28?C ? The ?G for the hydrolysis of ATP to AMP is ?31.6 kJ/mol.

What is K?
