Biochemistry
Enzymes, bonds and control: chemistry that has to keep a cell alive.
Most of this list is the vocabulary of the textbook and the bench, and much of it becomes transparent once a compound is read from the right: die Endprodukthemmung is inhibition by the end product. One verb deserves a warning. Konkurrieren looks like « to concur », and an English reader tends to hear agreement in it. It means to compete: Substrat und Hemmstoff konkurrieren um das aktive Zentrum, substrate and inhibitor compete for the active site, and adding more substrate tips the contest back its way. That is the whole idea behind die kompetitive Hemmung. The noun is die Konkurrenz, competition or one’s competitors, never agreement; to concur is zustimmen or übereinstimmen. The older sense of running alongside survives in one corner only, constitutional law, where die konkurrierende Gesetzgebung is concurrent legislative power: the states may legislate as long as the federation has not.
