You spray an insect with common insecticide that destroys the ability of acetylcholinesterase to recycle acetylcholine. What then happens? O The lack of recycled acetylcholine brings the cell metabolism to a halt. The insect loses control of body functions as nerve impulses flow continuously AND this prevents the synapse from restoring its ability to "reset" itself for the next impulse. O This kills the neuron directly. O This prevents the synapse from restoring its ability to "reset" itself for the next impulse. O The insect loses control of body functions as nerve impulses flow continuously.

A post-synaptic membrane O must be cell body membrane. O must be dendrite membrane. O can be either axon or cell body membrane. O can be either axon or dendrite membrane. O must be axon membrane. Neurotransmitters are molecules that cross the synaptic cleft and O either excite or inhibit the postsynaptic neuron. O always inhibit the postsynaptic neuron. O integrate the presynaptic action potential. O are carried along the membrane surface of the next neuron. O always excite the postsynaptic neuron. The likely effect on a neuron of two excitatory signals and twenty inhibitory signals is O confused integration. O transmission of a nerve impulse releasing excitatory neurotransmitters at the next synapse. O prohibiting the axon from firing at all. O transmission of a nerve impulse. O transmission of a nerve impulse releasing inhibitory neurotransmitters at the next synapse.
