...Motivation Caffeine is the world’s most commonly used psychoactive substance in the world. People have enjoyed and consumed caffeine as early as the 14th century. More than 60 plant species throughout the world have been identified as containing the chemical compound of caffeine. The wide spread natural occurrence of caffeine in many plant species has played a major role in the popularity of caffeine containing products (Baron and Roberts, 1996) such as chocolate and especially tea and coffee. Caffeine containing beverages made from native plants in South America, such as guarana, yoco, and mate, have been traced back to antiquity (Rall,1980).

Caffeine Sharpens Your Mind Wrong again! While caffeine users may feel more alert, the experience is really one increased sensory and motor activity (dilated pupils, increased heart rate, and high blood pressure).

...metabolic rates and what effect that has on each specimen on a biological level. The respiratory system’s main function is gas exchange as oxygen enters the lunges and travels to the alveoli for most reptiles and mammals. Insects however, do not have a gas transport system, leading to air traveling directly to the tissues carrying out respiration. The energy expenditure is directly linked to gas exchange in both humans and animals. Indirect calorimetry is used to determine the total metabolic rate by measuring both CO2 production and O2 consumption. Insects use spiracles, valve openings along the cuticle, in order to...

...1. The topic I choose to discuss is caffeine, particularly in coffee, there have been many studies to determine where it may be of benefit, and where it may cause undesirable effects. Some health benefits of caffeine are reduced risks of Parkinson's disease, a lower risk of developing gallstones, improved mental performance, physical performance, a reduced time of headzches, and improved heart health.

... ABSTRACT: The consumption of energy drinks is rapidly increasing, as demonstrated by their large market growth. The targeted demographic group is teenagers, young adults, 18 to 34 y old; although expansion into nontraditional markets is also occurring. It is claimed that energy drinks can offer an increased energy boost related to their ingredient profile of caffeine, taurine, herbal extracts, and vitamins. Research suggests that energy drink formulations, in addition to increasing energy utilization, may also improve mood, enhance physical endurance, reduce mental fatigue, and increase reaction time. However, in most cases, the corresponding mechanisms of action are not clear. In addition, concerns have been raised over their safety and with a currently weak regulatory environment, efforts need to be made to ensure consumer safety. The objective of this article is to review the current U.S. energy drink market with emphasis on its market size, target demographic, active ingredients, potential benefits, safety, and regulations.

...It is commonly known that caffeine, a nitrogenous organic compound generally found in coffee, tea, and cacao, has immense effects on the heart rate of living organisms. Similarly, it is known that those effects - such as a higher alertness, decreased fatigue, anxiety, jitteriness, etc. - are both pros and cons of caffeine consumption. While caffeine can have a slightly different effect depending on the organism that consumes it, the outcome of intake is primarily identical. Caffeine mimics some of the effects of adrenaline and noradrenaline in the heart, and affects the main pumping chambers - known as ventricles - leading to an increase in the rate of contraction and relaxation of each heart beat.
