How does viper snake venom work?
Snake venom has various types of enzymes which when introduced in the prey disrupt body cells' functions. A viper snake's venom contains neurotoxins â poisons, which act on the nervous system and block the conducting of a nerve impulse, paralysing the prey. Another enzyme called phospholipase ruptures the membranes of red blood cells inducing blood coagulation, which can be fatal.
