Final answer:
The drug Larissa took is categorized as a stimulant, because it increases the release of dopamine and norepinephrine in the brain, thus stimulating brain activity and enhancing alertness.
Step-by-step explanation:
Larissa has consumed a drug that works by increasing the amount of dopamine and norepinephrine that are released in the brain. The category of drug that increases the levels of these neurotransmitters is known as a stimulant. Stimulants act as agonists, meaning they can increase the activity of neurotransmitters either by promoting their synthesis or by preventing their reuptake in the synapses, which in turn stimulates the brain and increases alertness and wakefulness. Therefore, the drug Larissa took is most likely a stimulant, which includes substances such as caffeine, nicotine, cocaine, and amphetamines like Adderall. Stimulants work by increasing the amount of dopamine and norepinephrine released in the brain, which leads to increased neural activity and alertness. Examples of stimulant drugs include cocaine, amphetamines, cathinones, MDMA, nicotine, and caffeine.
