What is the primary mode of action of curare?
A)It causes the degradation of the enzyme acetylcholinesterase.
B)It decreases the amount of acetylcholine released from the synaptic terminal.
C)It decreases the number of functional receptors on the muscle cell by the process of phagocytosis, which impairs the ability of neurons to respond to acetylcholine.
D)It blocks communication at the neuromuscular junction by preventing acetylcholine from binding to nicotinic cholinergic receptors.
E)It blocks the sodium channels in the axon of the presynaptic axon.
