Question

Dendrotoxins, produced by the mamba snake, are inhibitors of the voltage-gated K+ channels. What phase of the action potential would this toxin affect? How would it affect ion permeability during this phase? How would ion movement be affected?

Answer 1

Dendrotoxins are type of the neurotoxins which block voltage gated potassium channales which enhances the production o fthe acteyl choline in the neuromuscular junction . It act at the resting memberane potential where the cell will be repolarizing the memberane , it produces the prolonged duration o fthe action potentials which results in the hyperexcitibilty and convulsive symptoms
