The venom of many cobras contains a potent neurotoxin that binds to ligand-gated Na+ channels, causing them to open. Unlike ACh, which binds to and then rapidly unbinds from ligand-gated Na+ channels, the neurotoxin tends to remain bound to ligand-gated Na+ channels. How does this neurotoxin affect the nervous system's ability to stimulate skeletal muscle contraction? How does it affect the ability of skeletal muscle fibers to respond to stimulation?

Several snake venoms contain toxins which blocks acetylcholine receptors at the neuromuscular junction. The presence of these toxins would directly interfere with the ability to: a initiate skeletal muscle contraction b relax cardiac muscle after contraction c control smooth muscle contraction d release acetylcholine from motor neurons e generate action potentials in motor neurons

α-latrotoxin, a neurotoxin in black widow spider venom, also affects acetylcholine (ACh) stimulation of muscle. Interestingly, organisms injected with α-latrotoxin exhibit uncontrollable muscle cramps and spasms, which after some time is then followed by complete flaccid (relaxed) muscle paralysis. Considering what you know about the botulinum neurotoxin, hypothesize how α-latrotoxin may modulate exocytosis of ACh.

40. Acetylcholine (ACh) is a neurotransmitter. When it diffuses across the synaptic cleft it binds with ligand-gated Na+ channels which causes depolarization. Would the following lead to more or less depolarization of the post-synaptic membrane? - Adding DDT, an insecticide that binds to the ligand-gated Na+ channels and locks them open. (More polarization or less depolarization) - Adding organophosphate insecticides that block the destruction of ACh. (More polarization or less depolarization) - Adding Botulinum toxin (Botox) which blocks release of ACh from the presynaptic neuron. (More polarization or less depolarization)
