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.
Green plants remove carbon dioxide from the atmosphere by photosynthesis.
Answer:
<h3>According to the Centers for Disease Control and Prevention (CDC), pets “increase opportunities for exercise and outdoor activities, [contribute to] better cognitive function in older adults, and [provide] more opportunities to socialize." Having a pet is also linked to health benefits such as decreased blood pressure, .</h3>
Answer: diaphragm
Explanation:
The diaphragm separates the thoracic cavity from the abdominal and pelvic cavity.
The diaphragm is a sheet of internal skeletal muscle located below the thoracic cavity that houses the heart and lungs. Below the diaphragm is the abdominal cavity.
The diaphragm plays an essential function for respiration. When the diaphragm contracts, the volume of the thoracic cavity increases so that air is drawn into the lungs.
