doesn't hold for yeast fermentation. Indeed, we do not as yet know suffi- 

 ciently accurately the sites of action of these two inhibitors to enable us to 

 visualize a mechanism. It may be confidently predicted that when different

tissues, different metabolic processes, different inhibitors, and different 

 ways of altering the metabolism are investigated, many types of effects 

 will be observed, and that one should certainly not conclude tliat inhibition 

 will generally increase with a rising metabolic rate.
