Action potentials travel down nonmyelinated axons at action potentials travel do

Question

Action potentials travel down nonmyelinated axons at action potentials travel down myelinated axons. slower speeds than faster speeds than the same speed variable speeds, sometimes faster and sometimes slower than the enzyme that breaks down acetylcholine within the synaptic cleft is acetylcholinesterase. monoamine oxidase. GABA. lipase. maltase. the sodium-potassium pump is primarily responsible for the resting potential. the action potential. the exaction of salts. the contraction of muscle fibers. maintaining isotonic water balance. A nerve impulse is the membrane potential of an inactive nerve. movement of a potassium ion all the way from dendrite to axon tip. movement of an electron all the way from dendrite to axon tip. an electrochemical change traveling a neuron. a change in the difference in sugar molecules on the outer and inner surfaces of the neuron membrane that opens adjacent channels. Neurotransmitters are molecules that cross the synaptic cleft and always inhibit the postsynaptic neuron. always excite the postsynaptic neuron. either excite or inhibit the postsynaptic neuron. integrate the pre-synaptic action potential. A and D are correct What happens if an insect is sprayed with a common insecticide that destroys the ability of acetylcholinesterase to recycle acetylcholine? the lack of recycled acetylcholine brings cell metabolism to a halt. the insect loses control of body functions as nerve impulses flow continuously This prevents the synapse from restoring its ability to "reset" itself for the next impulse. All of the above are correct B and C only are correct.
