Exoenzymes and toxins allow pathogens to invade host tissue and cause tissue damage. Exoenzymes are classified according to the macromolecule they target and exotoxins are classified based on their mechanism of action. Bacterial toxins include endotoxin and exotoxins. Endotoxin is the lipid A component of the LPS of the gram-negative cell envelope. Exotoxins are proteins secreted mainly by gram-positive bacteria.

Th...This page discusses how DDT accumulates in organisms through biomagnification across four trophic levels, resulting in higher toxin concentrations in top-level consumers such as ospreys and eagles. The slow metabolism and excretion of DDT lead to severe ecological consequences, including population declines in affected carnivores, as trace amounts in primary producers like plankton become exponentially concentrated as they ascend the food chain.
