Answer:
When an action potential reaches the end of an axon, the nervous terminal or the varicosities release neurotransmitters. These bind to receptors on the postsynaptic neuron. Eventually, the neurotransmitters are removed from the synapse. Some are reabsorbed by the presynaptic neuron or sending neuron, a process called reuptake, and some are broken down, in a process called enzymatic degradation.
Explanation:
Neurotransmitter liberation occurs from the nervous terminal or varicosities, in the neuronal axon. There are vesicles in the sending neuron that have neurotransmitters in their interior. When an <em>action potential reaches the nervous terminal</em> or the varicosities, it occurs a notable increase in the <em>neurotransmitter liberation</em> by exocytose. This is possible because calcium channels open letting the ion in the cell through the membrane, and letting the neurotransmitter out to the synaptic space. The molecule binds to its receptor in the postsynaptic neuron. This receptor is a <em>protein structure that triggers an answer</em>. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. <em>To stop this process</em>, the <em>neurotransmitter must be taken out from the synaptic space.</em> There are two mechanisms by which the neurotransmitter can be eliminated:
Enzymatic degradation/deactivation: In the synaptic space, there are <em>specific enzymes that can inactivate the neurotransmitter </em><em>by breaking it down or degrading it</em><em>.</em> In this case, the new molecule won’t be able to bind to the neurotransmitter receptor.
Reuptake: There are receptors located in the presynaptic membrane that can capture de molecule to store it back in new vesicles, for posterior use. These <em>transporters are active transport proteins</em> that easily recognize the neurotransmitter.
An outlier in human society means an extraordinary achiever.
One author, Malcolm Gladwell, theorized that 10,000 hours of work is the secret sauce for becoming an outlier.
My thoughts?Yes and no.
Example: I can't imagine someone with an 80 IQ having the same achievements in physics vs someone with an 150 IQ. Even if the low IQ person puts in 10,000 hours and the 150 IQ person only puts in 1000 hours.
A s solution that has more OH- than H+ is known as a basic solution.
<h3>What is an hydroxide ion (OH-)?</h3>
A hydroxide ion is a chemical ion the contains ions of hydrogen and oxygen with - 1 as it's oxidation number.
When a compound that contains excess OH- is added to a solution it will cause an increase in the basic nature of the solution.
This is because the OH- has the ability to accept protons when in a aqueous solution thereby leading to the rise in pH of that solution.
Increase in pH of a solution signifies an increase in basic characteristics.
