The neurotransmitter _ is hydrolyzed by monoamine oxidase:
Correct answer: B. Adrenaline
- A. Acetylcholine
- B. Adrenaline
- C. Serotonin
- D. Glutamate
Explanation
Monoamine oxidase (MAO) is an enzyme that breaks down neurotransmitters, including adrenaline (epinephrine), in the body. When adrenaline is released during stress or excitement, MAO helps regulate its levels by catalyzing its oxidative deamination, leading to its conversion into inactive metabolites. This process is important for maintaining neurotransmitter balance and preventing excessive stimulation of adrenergic receptors, thereby helping to modulate physiological responses such as heart rate and blood pressure.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
