The short term side effects to caffeine are restlessness, nervousness, insomnia and diuresis. Long term side effects to caffeine may be addiction, spike in blood pressure, depression, anxiety, and an ulcer irritant. 4. For the human investigation, the body system that would be observed is the nervous system. The test group would include men and women aged 16-25, all healthy and from any ethnicity.…
The results from this experiment show that caffeine can be extracted from a tea bag due to solubility properties of the natural substances found in tea. The two major substances that the caffeine was separated from are cellulose and tannins. Due to the insolubility of cellulose in water, it was easily extracted. Tannins are soluble in water but were neutralized with sodium carbonate to produce water-soluble salts. Caffeine is soluble in methylene chloride which allowed separation of tannins from caffeine because water-soluble salts are insoluble in methylene chloride.…
Caffeine, though addictive, has been a part of the human diet for years and years. In terms of stimulators for the central nervous system, caffeine at the top of…
Rachel Slee Mrs. Zamiara Honors Chemistry 9 March 2017 Chemistry of Caffeine Caffeine, or trimethylxanthine, is a compound in the alkaloid group. This compound forms its specific shape through the combination of carbon, hydrogen, nitrogen, and oxygen and is most commonly found naturally in tea, coffee, and cacao. It can also be synthetically made to be put into several energy drinks, or other caffeinated beverages. Caffeine is a polar molecule because the oxygen and nitrogen molecules within the compound have a stronger polarity than the carbon.…
The Lost Hour Journal Entry College students face a variety of difficult things during any single regular day of life. One important thing many college students face is the problem with not getting enough sleep. Studies show the average college student gets about an hour or two less than the adequate amount. In this passage I will compare my own sleep patterns to the findings of other studies.…
Caffeine is the perfect drug for the twenty first century world where everyone has their own race to win. One has to push oneself to the limit to achieve something, resulting in stress and exhaustion. Caffeine emerges as the drug to overcome stress, exhaustion and keep going that extra mile. Moreover caffeine is easily available and legal. There are many sources of caffeine readily available in the market, the major ones are coffee and energy drinks.…
Homework chap 3 lifespan Chap 3 Assignment Questions 1. Explain how sleep patterns are characterized over the course of life: infancy, childhood, adolescence/emerging adulthood and adulthood/aging (briefly for each of the 4 stages When we consider the sleep patterns during infancy, we have learned that newborns need approximately 16 to 17 hours a day but, some sleep more than others. Newborns sleep is sporadic: so the need to eat and to change diaper might modify the sleep pattern. Although, the range is from a low of about 10 hours or to high 21 hours per day.…
The drinks we have chosen for our project is water which will be our constant, sweet tea because it is a common drink in the south, and soda, which we will be using Dr.Pepper because it was the class favorite. Sweet tea contains 0.106 mg caffeine per ml of liquid, Dr. Pepper contains 0.116 mg caffeine per ml of liquid, and water contains 0.000 mg caffeine per ml of liquid. This means that the Dr. Pepper contains the most caffeine of the three drinks we have chosen ( Sinclair and Geiger, 2000). Caffeine “is a stimulant of the central…
When people sleep, their body rests and restores its energy levels. A good night sleep means to help you cope with stress, solve problems, or recover from illness. “Sleep is prompted by natural cycles of activity in the brain and consists of two basic states: rapid eye movement (REM) sleep and non-rapid eye movement sleep, which consists of Stages 1 through 4. During sleep, the body cycles between non-REM and REM sleep. Typically, people begin the sleep cycle with a period of non-REM sleep followed by a very short period of REM sleep.”…
Whenever a person wakes up a chemical called adenosine slowly accumulates in your brain. Adenosine binds to receptors which slow down brain activity. The more adenosine you have, the more fatigued your brain gets. The longer someone is awake, the more fatigued one will become, while sleeping the concentration of adenosine decreases slowly increasing wakefulness. ("Caffeine Withdrawal Symptoms: Top Ten,"…
The Effects of Caffeine on the Human Body By Gilary Lozano Lopez Worldwide, 70 to 76 mg of caffeine is consumed per person daily from food items such as coffee, soda, tea, and chocolate (Millerand Gilbert 1981). Caffeine generates a feeling of energy in the consumer after ingestion, accelerates the heartbeat and causes alterations in perception, mood, and consciousness. These alterations are caused by the blockage of adenosine, a chemical found in all cells in the body that promotes sleep (Nehlig et. al 1992). The consumption of caffeine has been linked to migraines, insomnia, nervousness, irritability, increased heart rate, and muscle tremors.…
Introduction The experiment was conducted as part of our stage 1 psychology unit on brain and behaviour where we explored the effects of caffeine on the reaction time of participants. Research surrounding caffeine is important to know the effects Caffeine affects the human body by increasing alertness and reduces fatigue as a result of stimulating the brain. In this experiment, the independent the amount of caffeine subjected to each individual in each group and the dependent variable was the reaction time tested and recorded for each person. There was 1 control group (group c) and 2 treatment group Treatment Group A and…
Caffeine is the most popular psychoactive drug in the world. Millions of people consume caffeine, in various forms, daily in order to feel more energized, but when consumed in amounts that are out of proportion, the effects can be counterproductive or dangerous. Caffeine is both a natural and man made substance that is classified as a drug, food additive, and stimulant of the central nervous system. Its chemical classification is Xanthines because it 's derived from the purine base Xanthine. Xanthine consists of a group of naturally occurring agents that act on the central nervous system.…
Once caffeine reaches the brain it begins connecting to the adenosine receptors in the basal forebrain. Caffeine is part of the xanthine chemical group much like the naturally occurring adenosine in the brain. Adenosine works by connecting with receptors, which in turn causes the body to sleep. When caffeine is taken the brain confuses it with adenosine and it binds with the sleep receptors rather than adenosine. This makes adenosine unable to bind with its receptors inhibiting sleep and causing the body to produce more adrenaline.…
