REGULATORY MECHANISMS OF CELLULAR RESPIRATION I
... The large number of inhibitors of cellular respiration hitherto described have been reported to act by inhibiting the activity of enzyme systems. They do so (1) by combining with the activating protein, either through some groups essential for activity (for example, the - S H groups), through denatu ...
