Effects Of The Heart Rate From Caffeine And Ethanol

The metabolism of an organism represents all bodily chemical reactions to intake, actions, etc (Reece, et al. 2011). Metabolism is often referred to as the energy of life, since it is either acting to conserve or expel energy of an organism. This can be measured mathematically through a series of experiments. Examples of metabolism are differences of the heart rate from caffeine and ethanol. By understanding the topic, it can be proven that these drugs affect organisms in a certain way, such as the heart rate. The information, collected following the experiment, can be inferred in recognizing the way our body responds to chemicals when drinking coffees and colas. The experiment was conducted by inducing the species Daphnia magna to both caffeine and ethanol, while being compared to a controlled group. Daphnia magna are small crustaceans, commonly known as water fleas, which are transparent making them easy to study their metabolism (Corotto et al. 2010). Since caffeine is a simulativ e and ethanol is a depressant, it assumed that the heart rate would increase with the exposure of caffeine and decrease with ethanol compared to control. This will occur not only in Daphnia magna, but also all other organisms. Material and Methods To conduct the experiment on the effects of caffeine and ethanol on the species, Daphnia magna, a set of instructions was followed laid out by the Shippensburg University of Pennsylvania Biology Department in the Laboratory Manual (Castle and PaulsonShow MoreRelatedDaphnia Lab Essay1153 Words   |  5 PagesDaphnia and Additives Lab Purpose The purpose of this lab is to test what effect of Nicotine, Acetylcholine, Epinephrine, Caffeine, and Ethanol on an organism’s heart rate. Materials * Microscope * Eye dropper * Pipet * Cotton balls * Depression slide * Beakers * Daphnia * Water * Five additives: Nicotine, Acetylcholine, Epinephrine, Caffeine, Ethanol Procedure 1.

Different Daphnia magnas were placed in a depression slide containing fresh water and later exposed to solutions of caffeine and alcohol. Each Daphnia magna had different responses. These data suggest there is an increase in heart rate when a Daphnia magna is exposed to caffeine and a decrease in heart rate when it is in a solution of alcohol.

It was investigated which substances act as stimulants and which substances act as depressant. Initially, _Daphnia_ was placed on depression slide under the microscope and the average heart rate was determined. Subsequently, _Daphnia_ was treated with different type of hormone and the effect on Daphnia heart rate was observed. It was investigated which substances act as stimulantsRead MoreEssay on Investigating the Effect of Alcohol on Heartbeat of Daphnia2284 Words   |  10 PagesInvestigating the Effect of Alcohol on Heartbeat of Daphnia Daphnia are the organisms that are involved in this experiment to find out what effect alcohol has on their heartbeat. It is easy to study the effects of alcohol on the heart of Daphnia as the organ can be easily seen through the transparent body of Daphnia. The number of heartbeats may be counted before submersion in alcohol and after submersion in alcohol to investigate the effect of alcohol. Daphnia belongRead MoreRecreational Drugs and Their Usage788 Words   |  3 Pagessociety nowadays. The usage of drugs can vary from medical purposes to recreational purposes. What is drugs? ‘A drug is any chemical you take that affects the way your body works.’ (Science Museum, What is a drug?, n.d.) So this does not mean that drugs can only be in the form of pill, tablet, oral solution, and injection drugs can also in the form of tobacco that contains nicotine, or drinkable substance such as coffee and tea that contains caffeine and beer that contains alcohol.

Alcohol is absorbed over almost the entire length of the digestive tract. Absorption from the mouth and oesophagus (canal between mouth and stomach) is minimal. Ethanol absorption from the stomach may vary between 10 and 30 %. The remainder of the ethanol is absorbed from the duodenum and small intestine. Overall, more than 90% of all alcohol consumed is absorbed, irrespective of the presence of food in the stomachRead MoreSleep Tight And Don t Let The Disorders Bite3239 Words   |  13 Pagessleep disorders: Insomnia disorder, Hypersomnolence disorder, Narcolepsy, Breathing-related sleep disorders (e.g., sleep apnea), and Parasomnias (e.g., nightmare disorder; Sprock O’Laughlin, 2013).
