Which natural substances are known sources of amphetamine?

• A. Ephedrine and caffeine
• B. Dopamine and serotonin
• C. Pseudoephedrine and ephedrine
• D. Norepinephrine and adrenalin

Answer: (C)

The correct answer identifies pseudoephedrine and ephedrine as natural substances that are known sources of amphetamine. Both of these compounds are derived from the Ephedra plant, which has been used in traditional medicine for various purposes, including as a stimulant and decongestant. In the body, they can be metabolized into amphetamines, which have stimulant properties similar to those of amphetamine itself. Pseudoephedrine is commonly found in over-the-counter cold medications, and ephedrine has historically been used in both medical settings and for performance enhancement or weight loss. These relationships highlight the significance of understanding how certain natural substances can be transformed into more potent stimulants and their implications for health and possible misuse. In contrast, other options include substances that either do not have a direct relationship with amphetamine synthesis or are neurotransmitters not associated with direct natural sources of amphetamine. Dopamine and serotonin, for example, are neurotransmitters that play roles in mood and reward but do not lead to the formation of amphetamine. Similarly, norepinephrine and adrenalin are also neurotransmitters involved in the body's stress response and are not direct sources for amphetamine itself.
