Show Answer
Answer:
Correct Answer: C
Solution:
Dopamine is a catecholamine secreted from adrenal gland. It acts as a neurotransmitter and precursor for norepinephrine. Deficiency of dopamine causes Parkinson’s disease in which muscles become rigid.
The neurons that secrete dopamine degenerate in this disease.
Excess amounts of dopamine cause schizophrenia in which a person’s ability to think and feel is affected.
The patient loses his ability to concentrate and the memory is also affected.
So, the correct answer is ‘Dopamine’.
