Caffeine more specifically belongs to the Xanthine family or alkaloids. Xanthines are known for their use as stimulants. They stimulate the Central Nervous System in turn causing heightened alertness and increased energy. Additionally, caffeine, falling under the Xanthine family, is also known to act as a diuretic, increases heart rate, and raises blood pressure. Due to these classifications and symptoms it is important to moderate the amount of caffeine ingested.
Does Caffeine Affect the Heart Rate of Daphnia? Introduction This experiment deals with the affects of caffeine on the heart rate of daphnia. The following includes information about daphnia and caffeine. Daphnia, also commonly called water fleas are small aquatic crustaceans. They are about 0.3 mm long which is about the size of this dot ( . )
Unit 9 Shigella Shigella infection (shigellosis) is an intestinal disease caused by a family of bacteria known as shigella. The main sign of shigella infection is diarrhea, which often is bloody. Shigella can be passed through direct contact with the bacteria in the stool. For example, this can happen in a child care setting when staff members don't wash their hands well enough after changing diapers or helping toddlers with toilet training.

The Effect of Caffeine on the Heart Rate of Daphnia Introduction In humans, caffeine acts as a stimulant drug, causing an increased heart rate. At high levels of consumption, caffeine has been linked to restlessness, increased stress and blood pressure. We decided to experiment on the effects of caffeine on daphnia and to see whether the same effects apply to their heart rate as they do to humans. Hypothesis As you increase the concentration of caffeine, the daphnia’s heart rate will also increase Ethical issues with using invertebrates We chose to use daphnia in our experiment, mainly for the practicality that they are transparent, so we were able to visibly see their heart clearly, making the experiment easy to be carried out. We also used them because they don’t have very complex nervous systems like other larger animals, meaning they don’t feel as much pain as some animals, such as dogs.
Isolating Caffeine from Tea Oct. 23, 2012 Abstract The purpose of this lab was to determine the concentration of caffeine from tea leaves through a simple extraction and sublimation process. With added ingredients including dichloromethane (DCM) and sodium carbonate to help separate and extract caffeine, the mass of the caffeine isolated was determined and compared to other products containing the same ingredient. Introduction Caffeine is found in many dietary products consumed everyday, coffee and tea being the most commonly known. Recent studies suggest that consumption of coffee in appropriate amounts may reduce the risk of certain diseases, however, there are many side effects associated with increased caffeine intake. Not only can the body undergo withdrawal because of its addictive tendencies, it can also lead to anxiety, insomnia, gastrotestinal disturbances and increased blood pressure (Nature, pg.
Trimyristin is found naturally in many vegetable fats and oils. Trimyristin is a white to yellowish-gray solid that is insoluble in water, but soluble in ethanol, benzene, cloroform, dichloromethane, and ether. It is a saturated fat which is the triglyceride of myristic acid. The purpose of this lab was to extract the fat trimyristin from the spice nutmeg by use of organic solvent, methylene chloride. Nutmeg comes from an East Indian tree.
