Differences between Exotoxins and Endotoxins

Differences between Exotoxins and Endotoxins

Differences between Exotoxins and Endotoxins Toxins are small molecules, peptides, or proteins produced by living cells that are capable of causing diseases or structural damage when they come in contact or are absorbed by tissues. Toxins and enzymes play important role in pathogenecity of pathogenic bacteria. Toxins may aid in invasiveness, damage cells, inhibit cellular processes, or … Read moreDifferences between Exotoxins and Endotoxins
