Phenol-Sulfuric Acid Analysis Essay

In our current era, sports is increasingly being incorporated in daily routines of individuals of all ages. Sports requires an enormous amount of energy. Is it possible to replenish this lost energy? Ever since the beginning of athletic competition, competitors have searched for a ‘legal’ tool that has the potential to enhance athletic abilities (speed, stamina, muscular endurance/recovery). A very common legal aid utilized is ergogenic aids which are subdivided into physiological, psychological, nutritional, pharmacological and mechanical ergogenic aids. Nutritional ergogenic aids otherwise referred to as anabolic enhancers are commonly used by a variety of athletes to enhance physiological performance. Isotonic drinks are frequently

The hands were washed. Goggles were placed on the eyes for extra protection. A petri dish containing nine pill bugs were obtained and set aside for later use. Two water bottles’ ends were cut and taped to each other creating a miniature tunnel for the pill bugs to crawl in. 50 mL of tap water was obtained in a small beaker and then was slowly moved into the lid of the bottle using a funnel. The sugar used in this experiment was created by mixing ten milliliters of starch,glucose, and regular countertop sugar. This was transferred into the joint water bottle tunnel using a funnel. Both ends of the tunnel were sealed shut and each measurements were taken every three minutes and final measurements were taken after 21 minutes. The results were

If one compares the amount of electrolytes present in an artificial substance (sports drink), to those in a natural substance (orange juice), then the natural substance will have the most electrolytes. That is my hypothesis. I chose this topic because I have always been skeptical about the validity of the quantity of electrolytes said to be in sports drinks. Sports drinks have been recommended as a way to replace electrolytes, which are lost during exercise. However, orange juice also has electrolytes and these are naturally occurring, not man made. Although water is also a liquid recommended for exercise, it is not used for strenuous exercise because it has no electrolytes. I predict that while running an electric charge through both orange

I would like to thank the people who were involved in my project would be my mom and dad who are helping me by buying the materials i need for my project. They also helped me by testing it at home.

Also Powerade is made of High Fructose corn syrup while Gatorade is made of sucrose, and high fructose corn syrup is known for causing many health problems making Powerade worse for you. It shows it right here, “The type of sugar in each drink differs, however...Gatorade contains sucrose, also known as table sugar, and dextrose... while Powerade’s sugar content comes from high-fructose corn syrup...high-fructose corn syrup is associated with health risks such as increased abdominal fat”(Derek). As you can see Powerade may be more unhealthy to you than Gatorade because of the the different types of sugar used. Lastly Gatorade has been proven to be a better equipped sports drink shown right here,“Gatorade contains 160 milligrams of sodium and 45 milligrams of potassium per serving, while Powerade contains 150 milligrams of sodium and 35 milligrams of potassium per serving. By comparison, Gatorade is slightly superior at replacing lost electrolytes.” As you can see Gatorade is better equipped for athletes proving the point that Gatorade is better than Powerade.

Gatorade and Powerade are sport drinks made for athletes to stay hydrated. Gatorade and Powerade have the same amount of sugar and carbohydrate content in it. Both drinks have a variety of flavour and mixtures to offer. In addition, both drinks contain vitamins, minerals, and electrolytes for better energy distribution. The results of this experiment will identify the better drink for endurance.

The results do not support the hypothesis that a higher surface area to volume ratio would result in sulphuric acid being diffused into the agar cubes in the shortest amount of time. This is evident in the results as the exact opposite to what was predicted occurred. Instead of the smallest cube with the largest surface area to volume ratio of 1cm3 having the quickest diffusion rate, it conversely took the longest at 0.092 cm3 per second, whilst the 2cm3 cube with 0.0384 cm3 per second took the least amount of time. This directly refutes the hypothesis. There was also no consistent trend evident in the results. Between the two largest blocks of 2cm3 and 3cm3, there was only a 0.00243 cm3 per second, however, and in contrast to the hypothesis,

In this experiment, one tested solutions that consisted of the standard yeast solution and added raw materials of interest. First, one measured and then added seven grams of Fleischmann 's Rapid-Rise yeast to a bottle containing two hundred and fifty milliliters of warm distilled water for the purposes of creating the standard yeast solution that was used in the fermentation experiment. Next, the standard yeast solution was added to each of the four fermentation flasks. After swirling the bottle, one and a half grams of the fermentation substrate was added into a beaker with fifteen milliliters of yeast suspension. The fermentation flask marked one required one and a half grams of Zulka Brand Morena Pure Cane Sugar as the fermentation substrate, the fermentation flask marked two required one and a half grams of Maseca Brand Corn Flour as the fermentation substrate, the fermentation flask marked three required one and a half grams of Carolina Biologicals Glucose as the fermentation substrate, and the fermentation flask marked four required one and a half grams of distilled water as the fermentation substrate. Then, the opening of each fermentation flask was covered with parafilm and one proceeded to gently mix the solutions. The part of the fermentation flask with calibration marks must be filled with the yeast suspension so that there is no empty space. Next, one placed the fermentation flasks in the water bath and recorded the carbon dioxide volume readings after the

Most sugar consumption comes from different beverages like soda, sports drinks, coffee, juice, and energy drinks. The sugar content in a beverage is based off of the size of the beverage. Some of the different sizes are 8 ounces, 12 ounces, 16 ounces, and it goes on. According to livestrong.com, “A 12-ounce can of regular Coke contains 39 grams of total sugar” (Melodie Anne, 2017). That is a lot of sugar just for a can of Coke. Many other sodas contain similar amounts of sugar content in them if they are not diet or zero sodas. Another beverage that has a lot of sugar is sports drinks. Gatorade was invented at the University of Florida and it is made for elite athletes that actually need to consume it for sweat loss. An article by ABC News Medical Unit claims, “Athletes should only drink beverages like Gatorade in combination with water after prolonged, vigorous activity when they need to quickly replenish electrolytes” (Kim Carollo). The problem is sports drinks are easily available to people and they are always drinking them. Kids especially don’t need to be drinking

When the 1970s introduced High Fructose Corn Syrup (HFCS), a cheap sweetener alternative to sucrose in a fructose-glucose liquid form (fifty five percent fructose, forty two percent glucose, and three percent saccharides), it brought extensive numbers of health problems with it (Bray, 2004 & Johnson, 2010 ). Prior to the 70’s, on average, sugar contributed to four percent of daily caloric intake, however over the past four and a half decades, this statistic has increased to whopping sixteen percent, leading some scientist to consider it an “addiction” as they observe the sugar substitute wreak havoc on humans’ bodies worldwide (Butler, 2011). Along with hooking those who indulge sweets to it, High Fructose Corn Syrup also leads to obesity:

The production of fructose corn syrup is handled by a variety of individuals from the moment the crop is harvested. The farmers that grow the corn have little control of where the corn ends up. After the harvest, the corn is stored in a grain elevator until it is distributed. Once it is distributed it goes through a series of processes in order to reach its final state. As the documentary shows, the production of high fructose corn syrup is regulated and there are a variety of steps and ingredients that go into the production. The final product is then used as a sugar substituted for many sodas and

Dr. Lustig’s main focus throughout the presentation was the effects of fructose on the epidemic of obesity. He explains how we as a society place so much stress on fat intake and calories in versus calories out that we tend to neglect what is actually in our food. With much research, it has been determined that fructose does, in turn have an effect on the obesity epidemic. Throughout the lecture, many examples from this research show our biochemical response to our modern diets and are used to explain Dr. Lustig’s point of fructose poisoning.

Robert H. Lustig’s article “The toxic truth about sugar” centers around the author attempting to prove the truth in the title. The negative health effects of today’s sugar consumption can no longer be ignored he argues. It's time to act against sugar like we've acted against tobacco and alcohol. From the article the problem with sugar isn’t just weight gain. Authorities consider sugar as 'empty calories' — but there is nothing empty about these calories. A growing body of scientific evidence is showing that fructose can trigger processes that lead to liver toxicity and a host of other chronic diseases. The purpose of this article is alert people sugar is bad for human body. A little sugar is not a problem but a lot sugar will

Sugary drinks are a major contributor to the obesity epidemic. The term “soft drink” refers to any beverage with added sugar or other sweetener, and includes soda, fruit punch, lemonade and other sweetened powdered drinks, and sports and energy drinks. People who drink sugary beverages do not feel as full as if they had eaten the same calories from solid food, and studies show that people consuming sugary beverages don’t compensate for their high caloric content by eating less food.
