Which neurotransmitter is hydrolyzed by the enzyme monoamine oxidase (MAO)?
MAO breaks down monoamine neurotransmitters: dopamine, serotonin (5-HT), adrenaline, noradrenaline. Acetylcholine is broken down by acetylcholinesterase; glutamate is not a monoamine.
How many grams of COâ are produced by thermally decomposing 10 moles of ZnCOâ? \(\mathrm{ZnCO_3 \rightarrow ZnO + CO_2}\)
1 mol ZnCOâ â 1 mol COâ. Molar mass COâ = 44 g/mol. Mass = 10 Ă 44 = 440 g. Option d (440 g).
A motor neuron transmits impulses:
Motor (efferent) neurons carry signals from CNS to effectors (muscles/glands). Sensory (afferent) neurons carry signals from receptors to CNS. Interneurons connect within CNS.
