Consider these hypothetical chemical reactions: A⇌B,ΔG= 13.7 kJ/mol B⇌C,ΔG= -27.2 kJ/mol C⇌D,ΔG= 6.20 kJ/mol What is the free energy, ΔG, for the overall reaction, A⇌D? Express your answer with the appropriate units. ΔG = 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...
