Final answer:
The correct sequence of events for nerve transmission at a cholinergic nerve terminal is binding of acetylcholine to receptors, followed by enzymatic degradation, and finally reuptake into the presynaptic neuron, which corresponds to option b) Binding, degradation, reuptake.
Step-by-step explanation:
Steps of Nerve Transmission for a Cholinergic Nerve Terminal
The steps of nerve transmission at a cholinergic nerve terminal involve the neurotransmitter acetylcholine (ACh). Initially, ACh is released from the presynaptic neuron into the synaptic cleft and subsequently binds to ACh receptors on the postsynaptic membrane. Once the signal is passed, ACh must be removed from the synaptic cleft to reset the postsynaptic membrane. This is achieved through enzymatic degradation, where ACh is broken down by the enzyme acetylcholinesterase. In addition, ACh can be removed from the synaptic cleft through reuptake, where it is absorbed back into the presynaptic neuron.
Therefore, the correct sequence of events after ACh release is: Binding to receptors, enzymatic degradation, and then reuptake. This makes option b) Binding, degradation, reuptake the correct sequence for the steps of nerve transmission in a cholinergic nerve terminal.
