Be 
believe that in fermentation we deal with an exaggerated anaerobic 
respiration, the active ferments being plants in which zymase is 
produced in such amounts that it can attack sugars outside the organ- 
ism, and thus secure sufficient energy with a minimum destruction 
of the protoplasm. 
ENERGESIS. 
Finally, I may suggest that for didactic purposes it is desirable — 
to have a word other than “respiration” to designate the disruptive — 
processes by which energy is released, leaving “respiration” to- 
designate the more superficial phenomena of aeration with whi 
plant physiologists are but little concerned. Perhaps the word 
“respiration” is already too firmly imbedded in literature to be so_ 
limited. It will at least do no harm to propose that the terms 
“aerobic and anaerobic energesis” be considered, to which “fer- 
mentative energesis” may be added if necessary. |
