Teachers Notes:

Problem 1:
a. Intermediates: Luciferyl adenylate-luciferase
Catalyst: luciferase
b. luciferine + ATP + O₂ → pyrophospate + oxyluciferin + AMP + light
c. A = reactants, A* = activated complex, B = products

Problem 2:
Intermediates : C₆H₅OC₂O₄H, C₂O₄, [CO₂] ^{· -} , [C₄₂H₂₈]· ⁺, [C₄₂H₂₈]*
Catalyst: C₄₂H₂₈
Complex reaction: C₁₄H₆N₄O₁₂+ H₂O₂ C₄₂H₂₈ → 2 C₆H₅OH + CO₂ + hν (light) + products

Problem 3:
a. Intermediates: I, F*
Catalyst: Fluorophor (F)
b. A catalyst lowers the activation energy for the reaction.
