Microbiology
Exotoxins are lipid molecules, while endotoxins are proteins.
Exotoxins are secreted outside of bacterial cells, while endotoxins are found within bacterial cells.
Exotoxins are exclusively produced by gram-negative bacteria, while endotoxins are produced by gram-positive bacteria.
Exotoxins are resistant to enzymatic degradation, while endotoxins are easily broken down.
