Answer:
The correct answer is C) <em>Acetylcholinesterase.</em>
Explanation:
Neurotransmitter release occurs in the neuron axon. The sending neuron has vesicles filled with neurotransmitters in their interior. When an action potential reaches the nervous terminal or the varicosities, it causes the neurotransmitter release by exocytose forward to the synaptic space. The molecule binds to its receptor in the postsynaptic neuron. This receptor is a protein structure that triggers an answer. As long as the acetylcholine is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. To stop this process, the neurotransmitter must be taken out from the synaptic space. There are two mechanisms by which the neurotransmitter can be eliminated:
- <em>Enzymatic degradation/deactivation</em>: In the synaptic space, there is a specific enzyme called Acetylcholinesterase that can inactivate the neurotransmitter by breaking or degrading it. In this case, the new molecule won’t be able to bind to the neurotransmitter receptor.
- <em>Reuptake</em>: There are receptors located in the presynaptic membrane that can capture de molecule to store it back in new vesicles, for posterior use.
Answer:
The answer is E
Explanation:
Work has been done on the functions of RNA over the years involving a group of scientists and their teams.
These scientists include Brenner, Crick, Meselson, as well as Watson.
There were limitations to establishing the functions of RNA, one of which access to more primitive techniques, machines and equipment stands out.
This limited the amount of knowledge scientists had access to about RNA but as time went by , the function of RNA was established to be linked to DNA.
Better technology provided better techniques to determine how much DNA is expressed and how much RNA functions in translating and transcribing the information carried in DNA which in turn, provides a template for the functions of the RNA present in cells.
Mimicry, this is an organism exhibiting characteristics similar to one known to be dangerous.
You’ll have to also provide pics from the article the question is talking about Bc it’s asking for evidence from the article which you didn’t show lol
