Caffeine Experiment

It is one of the few articles that I have that cover long term effects of caffeine consumption which is one of the things that I wanted to cover in my final paper. This source does show me that there is some link between the reward system for caffeine consumption and caffeine addiction/dependence. This article has provided me with the basic pharmacology for caffeine. This is especially useful because it really breaks down the information, and I think I will be able to understand it within a year. The basic pharmacology will give me what I need to be able to introduce the caffeine pharmacology for my paper. Overall, this is by far the most useful source that I have ever

Metabolism is the sum of all anabolic and catabolic reactions within a living organism to sustain life. The energy required to perform these reactions is provided by oxygen in the form of ATP, therefore the oxygen consumption rate can be measured to determine the metabolic rate. Since oxygen is obtained through respiration, the efficiency of an organism’s respiratory system affects its metabolism. Previous studies have shown that caffeine affects the human respiratory center and occasionally dilates bronchus. It can thus stimulate human respiration and increase the metabolic rate (Haggins et al, 1915).

Do you start your day with a fresh, steaming cup of coffee? Perhaps because you need caffeine to keep you awake or energized through the morning hours. Do you drink coffee to satisfy your addictive thirst? Yes, will be the common answer to this question for majority of Americans. According to a research done by Villanova University,“90% of Americans consume caffeine every single day either knowingly or in some instances unknowingly” (1). According to a 2015, article from “MEDICALNEWSTODAY”, excessive and over dependence on Coffee to kick start one’s day or even to be productive can lead to addiction and consequently serious health concerns; as a result, I am of the firm believe, as a preventative measure, that Coffee should be consumed in moderation if at all.

According to Keith Ablow’s “The Dangers of Cramming”, cramming can do more harm than good because of its negative effects to our mind and body. Such side effects are temporary intellectual lapses which causes a person to lose focus. However, this effect differs to everyone since each of us has different requirement for a full good night’s sleep. Ablow mentions that though students think that stimulants will help them cram, they actually don’t, it actually just “… disguise – briefly – a reduced capacity to grasp, retain, and retrieve information” (Ablow 5). Coffee causes Caffeine Intoxication Syndrome which leads one to have anxiety, panic, headaches, and insomnia. A much stronger stimulant, speed (an amphetamine), causes more severe side effects

1. 150 ml of boiled water was poured into each of the three beakers labeled A, B, C.

The results that we concluded were the same with what we expected from our hypothesis. The Daphnia heart rate increased higher as it was placed in the various solutions of caffeine. The heart rate had a decrease as the Daphnia was exposed to the alcohol. This experiment helps understand how cellular biology works in a controlled environment. We also learn and understand the effects of alcohol and caffeine does to our body and health. Not just human but animals and other organisms as well. Daphnia biology still showed a reaction even though we tried the experiment on a smaller scale a larger scale. Daphnia biology showed the same reaction the exact way a human would when exposed to a stimulant or

Many consumers agree that energy drinks actually provide the human body with the desired energy. The reason behind this effect is caused by the high amounts of caffeine and sugar. Whenever a consumer uses an energy drink a series of effects begin in his/her body. The organism receives an instant boost as the caffeine successfully manages to block the duties of the adenosine, a chemical located in the brain whose function is involved with sleeping. After the completion of the process caffeine forces part of the neurons in the brain to lighten up, which later on causes the body to release the hormone adrenaline. When the hormone is active it forces the liver to provide the bloodstream with additional

A vital "knowledge gap" is addressed in this experiment, that is to study the effect of stimulants and depressants, such as ethanol, melatonin, epinephrine, and dopamine on HR, individually and in a mixture. Said depressant and stimulant chemicals were administered to daphnia individually and afterwards, in combinations. The motivation for research in this area was to explore whether two select depressants or stimulants when administered together have a synergistic, antagonistic or no effect on HR. Data was determined in the form of Beats Per Minute (BPM). The data was analyzed by plotting the calculated BPM for each test solution from each daphnia. This study was designed to discover the effect of the chemicals on daphnia HR. The results of

It is absorbed through the stomach and reaches the highest level in the bloodstream after one or two hours. Caffeine reaches the brain quickly and acts as a stimulant for the nervous system. The most noticeable effect of caffeine is alertness. It causes us to feel less tired, so it is a main ingredient in medicines designed to prevent exhaustion. Unfortunately, it is possible to have an overdose of caffeine or a caffeine withdrawal. If too much caffeine is ingested, it can cause hallucinations and confusion. If someone is used to having caffeine on a regular basis, and then doesn’t have it for a while, it can cause irritability, drowsiness, nausea, and anxiety. Caffeine can also cause raised levels of stomach acid, which can cause heartburn. It is not a good thirst quencher because it signals your body to get rid of water. Surprisingly, additional caffeine is not stored in the body. The liver processes it and it exits through urine. Caffeine can also affect the skeletal systems. Ingestion of large amounts of caffeine can interfere with the absorption and metabolism of

In chapter eight, caffeine, Natterson beings by defining what caffeine is and how popular it 's become. The natural stimulant, caffeine, is found in several plants such like the tea bush, the coffee plant, the cacao tree, and the kola tree. When a person consumes caffeine, it affects the neurons in their brain causing the feeling of energy and awakeness. This happens because the neurotransmitter, Adenosine, is meant to control and us down; but when it meets caffeine, caffeine

I. The world consumes about 2.25 billion cups of it every day, it is also the world’s second most valuable traded commodity, and drinking it can improve blood flow.

In today 's society, if we appear to be exhausted, while knowing that we have to be on the run, we turn ourselves to energy drinks. Little do we know that every time we consume a single sip of an energy drink, we are literally creating a crucial complication towards our body. The innumerable quantities of caffeine and sugar that we devour stimulates each and every part of the body. Individuals have been replacing protein bars and other athletic beverages for real food (McCarthy). Becoming addicted to energy drinks relates to type 2 diabetes, even long-term effects such as heart issues, but most of all death. It is urgent that we pace the amount of caffeine from energy drinks that we ingest on a daily basis.

Caffeine is a chemical found naturally in few plants all over the world. From these plants it is processed into its pure form and then put into other things such as soda, energy drinks, tea, and pills. Energy drinks and soda are some of the most widely marketed products in the world, even though they contain the highest concentration of caffeine outside of pure caffeine supplements. It is a stimulant that affects everyone in strange but semi predictable ways. Research has been done on this topic since the 1920’s and many different conclusions have been reached. In modern schools of thought, caffeine has been found to be a lightly addictive, moderate to severe stimulant that affects neurological function in various ways, though scientists disagree

Rachael C. Gliottoni and Robert W. Motl wrote the article entitled “Effect of Caffeine on Leg-Muscle Pain during Intense Cycling Exercise: Possible Role of Anxiety Sensitivity” focuses on the possible effect of caffeine on the opinions of leg pain. Published by the International Journal of Sport Nutrition and Exercise Metabolism, the researchers had sixteen college-age women drink moderate dose of caffeine or equivalent to 5 mg/kg body weight as placebo. After one hour, Gliottoni and Motl also asked the participants of the research to complete cycling on an ergometer for 30 minutes.
