Show Answers

They consist of protein moleculesThey are sensitive to heat and easily destroyedThey provoke a strong immune responseThey trigger the complement system via the alternative pathwayThey are secreted actively by bacteria

Explanation

Endotoxins are distinct from exotoxins because they activate the complement cascade through the alternative pathway, whereas exotoxins are typically proteins that are heat sensitive and strongly antigenic.
