Relation to General Respiration

Bacterial luminescence is somewhat resistant to the action of cyanide 

Luminescence is more sensitive than respiration to small concentrations of mercuric chloride. The amount of inhibition by this agent depends upon the concentration of the cells as well as that of the inhibitor. 

There seems to be no reason to doubt that this scheme is fundamentally 

In the figure, the free energy which each system liberates is indicated as two hydrogens, or two electrons plus two protons, which are liberated to form water. Constricted tubes indicate the chemical inertia of processes which may be much further inhibited by agents such as urethan or cyanide, indicated opposite the sensitive pathway. Presum- 

It is necessary to postulate at least two autoxidizable enzymes. This is in accord with the view that has been held by Harvey and co-workers, on the basis of differences in the temperature-activity curves of luminescence and total oxygen consumption, as well as differential effects of inhibitors and other factors (170,171,1 5,180).
