Toxinsany poison produced by an organism, characterized by antigenicity in certain animals and high molecular weight, and including the bacterial toxins that are the causative agents of tetanus, diphtheria, etc.,
and such plant and animal toxins as ricin and snake venom.
Rates of ReactionsAre affected by temperatures:
Colder temperatures slow down reactionsWarmer temperatures speed up reactionsAs pH decreases so will reaction rates
