Caffeine present in the coffee is a/an
A) Sedative
B) Antidepressant
C) Stimulant
D) Psychedelic
Solution
Coffee is a brewed beverage made from roasted coffee beans, which are the seeds of some Coffea species' berries. Coffee berries are collected, processed, and dried when their colour changes from green to bright red, signalling ripeness. Depending on the desired taste, dried coffee seeds are roasted to varying degrees.
Complete answer:
How does caffeine work?
Caffeine is easily absorbed from the gut into the bloodstream after consumption.
It then moves to the liver, where it is broken down into compounds that can influence the function of different organs.
It works by inhibiting the effects of adenosine, a neurotransmitter that relaxes the brain and makes you sleepy.
Normally, adenosine levels rise during the day, leaving you exhausted and unable to sleep.
Caffeine keeps you awake by binding to adenosine receptors in your brain but not stimulating them. This inhibits the effects of adenosine, resulting in less tiredness
Caffeine is a methylxanthine-class psychoactive drug that stimulates the central nervous system. It is a bitter, white crystalline purine that is a methylxanthine alkaloid and therefore chemically similar to the adenine and guanine found in DNA and RNA.
So, Caffeine present in the coffee is a Stimulant option C is correct
Note:
Caffeine doses of up to 400 milligrammes (mg) a day tend to be safe for most healthy adults. That's about the caffeine content of four cups of brewed coffee, ten cans of cola, or two "protein shot" drinks.
