Introduction:
The Coca Cola company has advertised the claim that their sports drink, Powerade Zero, contains zero sugar. This claim will be further examined through experimentation to prove whether or it is factual. This will be then compared to Powerade Ion 4 and the amount of glucose which is in the drink will also be determined. To obtain a quantitative measure of how much glucose is present in Powerade Zero and Powerade Ion 4, a spectrometer will be used to measure the colour change from adding Benedict’s to the drinks.
Glucose (C6H12O6) is most common form of sugar, a type of carbohydrate and consists of six carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. During an oxidation process, labelled as metabolism, glucose produces 2870

(Ausetute.com.au, 2016) A redox reaction is a type of chemical reaction which occurs when electrons are transferred between substances during a reaction. The reducing reagent is the substance which causes reduction and therefore loses electrons whereas the oxidising reagent is the substance which causes oxidisation therefore gaining extra electrons. (Chemwiki.ucdavis.edu, 2013) These reactions occur simultaneously with each other however for this to transpire a reducing sugar is …show more content…
This error was that the colorimeter could not produce an accurate measurement of the absorption or concertation as the solutions weren’t filtered enough leading to the large amount of suspended solids in the solutions. To resolve this instead of using filter paper to remove the copper I oxide, a manual centrifuge was used a replacement. By using the centrifuge, the suspended solids were gravitated to the bottom of the test tube therefore the colorimeter could produce an absorption and concertation. To improve this rather than using filter paper to remove precipitates from a solution a centrifuge will be used to remove
Briefly describe an alternative technique that could be used to measure the amount of glucose within sports drinks. (5 points)
ε should be all same for three experiments so error occurred here. Source of this error might be little water or moisture inside colorimeter before starting new experiment. This could affect absorbance of wavelength by colorimeter. Also, I used 45°C graph to determine the order of ferroin because when I plotted all three graphs for 40°C, zero-order graph had higher percentage of R^2, than first-order graph. It must have been human mistake as my lab partner forgot to measure for every 120 seconds but randomly recorded four points instead. (120, 240, 430, 540)
With respiration of carbohydrates, the food is then converted to carbohydrates usually hexose sugar before being respired. There is an oxidation of glucose to carbon dioxide and water with the release of energy.
... samples before the incubation of 108 seconds. Then the 100 µL of colour reagent was put to the sample, merged and incubated for further 10 minutes. The absorbance at 615nm and 700nm wavelengths was calculated on the samples in the Cobas analyser and the sample concentration was measure according to :
Gatorade and Powerade are two common sports drinks. Many people wonder which drink is healthier. Gatorade and Powerade have the same number of calories and sugars. But the type of sugar used in each drink differs. Gatorade uses sucrose, also known as table sugar. On the other
Sports drinks are used to supplement the loss of electrolytes, water and energy after exercise, helping the athlete recover quicker by replacing the key ionic-substances back into the body. They are designed to give the athlete an equal amount of carbohydrates and fluids to provide an almost instant rehydration and refuel during physical activity. This essay will explain the purpose of the contents of sports drinks and their uses in the human body.
My hypothesis for this experiment was that the sports drinks would be the substance with more electrolytes, in particular the Maximus sports drink as other people who have conducted experiments of sports drink have found Maximus to have more electrolytes to other sport drink brands such as PowerAde
An enzyme is a catalysis and catalysis s substance that increases the rate of a chemical reaction without itself going through a permanent chemical change. In this lab we will discover exactly how the substrate connects with the active site. The main substance we use throughout this lab is peroxidase a eukaryotic organelle from plant tissues. Once there is a color change we test that using a spectrophotometer. Introduction
Both Powerade and Gatorade refreshments hold numerous carbohydrates in the structure from claiming sugar fruit that replenishes vitality Throughout alternately then afterward An workout. The unique “Thirst Quencher” Gatorade and the conventional Powerade brands every hold 21 grams of sugar fruit for every 12-fluid-ounce serving, making them equivalent suppliers of the undoubtedly edible supplements. The kind of sugar fruit in every drink differs, however. Gatorade holds sucrose, otherwise called table sugar, Furthermore dextrose, another basic sugar compound, same time Powerade’s sugar fruit substance hails from high-fructose corn syrup. Investigations bring not definitively demonstrated that particular case sugar fruit is superior to alternate Throughout An workout, in any case high-fructose corn syrup may be connected with
The materials used in the previous were cleaned and dried. 10ml of CV was obtained along with 10ml of sodium hydroxide. These solutions were separately diluted to 50ml. A stopwatch was set up to record in 30second increments and the Spectrophotometer prepped for the cuvette. The following steps were done within 30seconds. The two solutions (CV and sodium hydroxide) were mixed in a large beaker. A pipette was used to deliver the solution into a test tube serving as the cuvette. The absorbance was recorded every 30second until 15minutes had passed and entered into a spreadsheet. All used materials were cleaned for the next trial.
Oxidation-reduction reactions can be used to stereochemically control and produce many different organic molecules. The oxidation step in this process increases the number of carbon oxygen bonds by losing a hydrogen and breaking that bond. Through the reduction step, carbon-oxygen bond is broken and the hydrogen is returned.
From the Results there is an anomaly which is with the test tubes at 58oC, the results spike from 0.100 to 0.536 and then back down to 0.302, this anomaly may have happened due to the three samples in the test tubes potentially having a higher level pigment in the vacuole than the other

Glucose is the fuel cells use for respiration, carbon dioxide. Glycolysis occurs in the cytosol and creates two 3-carbon molecules of pyruvate and two molecules of ATP by breaking down glucose. During the aerobic process, pyruvate will lose one of its three carbons as a molecule of 〖CO〗_2, leaving behind a two-carbon acetyl group. Oxygen is re...
Carbohydrates are the main source of glucose, which is a major fuel for all of the body's cells and the only source of energy for the brain and red cells. Except for fiber, which cannot be digested, both simple and complex carbohydrates are converted into glucose. The glucose is then either used directly to provide energy for the body, or stored in the liver for future use. When a person consumes more calories than the body is using, a portion of the carbohydrates consumed may also be stored in the body as fat.
