11 Questions
Which of the following is true about the transport of choline into the cytoplasm of the cholinergic neuron?
It requires the presence of sodium
What is the role of sodium in the transport of choline into the cytoplasm of the cholinergic neuron?
It is required for the energy-dependent carrier system
Which drug can inhibit the transport of choline into the cytoplasm of the cholinergic neuron?
Hemicholinium
Which of the following is true about the transport of choline into the cytoplasm of the cholinergic neuron?
The transport of choline is facilitated by a carrier system that cotransports sodium ions.
Which drug can inhibit the transport of choline into the cytoplasm of the cholinergic neuron?
Hemicholinium
What happens to the transport of choline into the cytoplasm of the cholinergic neuron when the carrier system is inhibited by hemicholinium?
The transport of choline stops completely
Which of the following is the rate-limiting step in acetylcholine synthesis?
The uptake of choline
What is the significance of the rate-limiting step in acetylcholine synthesis?
It determines the overall rate of acetylcholine synthesis
What happens if the uptake of choline is inhibited?
The synthesis of acetylcholine is reduced
Which of the following is the rate-limiting step in acetylcholine synthesis?
The transport of choline into the cytoplasm
What happens if the uptake of choline is inhibited?
The production of acetylcholine is reduced
