Given below are two statements:

Statement I : Noradrenaline is a neurotransmitter.

Statement II : Low level of noradrenaline is not the cause of depression in human.

In the light of the above statements, choose the correct answer from the options given below

<p><b>Statement I:</b> Noradrenaline is a neurotransmitter.</p> <p>This statement is correct. Noradrenaline is a type of neurotransmitter, which are chemicals that help transmit signals from one nerve cell to another. Noradrenaline is produced and released by nerve cells and acts on other nerve cells, as well as on various organs and tissues in the body, to regulate important functions such as heart rate, blood pressure, and alertness.</p> <p><b>Statement II:</b> Low level of noradrenaline is not the cause of depression in human.</p> <p>This statement is incorrect. Although depression can be caused by a variety of factors, low levels of noradrenaline have been linked to depression in some cases. Studies have shown that individuals with depression often have reduced levels of noradrenaline in certain areas of the brain, leading researchers to believe that a deficiency in this neurotransmitter may contribute to depression. However, it is important to note that depression is a complex disorder with multiple causes, and low levels of noradrenaline may not be the sole cause of depression in all individuals.</p>
