I. Science Fair Question How does an enzyme convert sucrose into glucose and how we digest glucose from different foods?
II. Background Research The idea of this project is to test drinks and foods by dipping a urinalysis test strip into them and see how much sugar is in each drink and food. This project will measure two sugars, glucose and sucrose in different foods. It can help prove that too much sugar is not healthy and how our bodies digest them. The important terms that will be discussed in this paper are glucose, sucrose, fructose, sugar, and diabetes. Sugar is any class of crystalline carbohydrates such as sucrose, glucose, or lactose, that dissolve in water and have a characteristic sweet taste (The American Heritage Student Science Dictionary 331). When foods or drinks are sweet it is most of the time from sugar. There are many different types of sugars which are called carbohydrates (chemical compounds that only have carbon, hydrogen, oxygen and mostly made by different plants). Sucrose is a different name for sugar (Sucrose and Glucose and Fructose, Oh My! Uncovering Sugar in your Food).

Sugar, starches, and cellulose are all carbohydrates (The American Heritage Student Science Dictionary 57). Carbohydrates are just a fancier way of saying “sugar”. It’s called an organic compound because it is made up of one long chain of carbon atoms. They provide living things with energy and can act as substances that are used for structure. When multiple carbohydrates combine they change to polysaccharide. They may also be very large or very small molecules
Sucrose and maltose were the two sugars under investigation. The total of six groups was divided into three experimenting with maltose and three experimenting with sucrose. Begin the experiment by weighing 10 grams of bakers yeast and adding it to 66 mL of deionized water into the side arm
In this experiment the four different types of sugar substitutes will be tested with yeast to determine if the type of sugar substitute directly affects the respiration rate of yeast. The four different types of sugar substitutes include Saccharin (Sweet ‘N Low),
When we learnt about Carbohydrates in the Option B chemistry class, we learnt about the disaccharide sucrose, also known as the table sugar we know. We got into a lengthy conversation on the health benefits and hazards of this sugar and in doing so, we factored in the wide intake of soft drinks around the world especially Coca-Cola that my teacher described as very sugary. I personally enjoy a very cold soft drink. However, I once had to buy a moderately

Carbohydrates are sugars and starches and are made of monomers called saccharides, which are connected together to make a polymer called polysaccharides. Carbohydrates give energy to living things, and a special type of carbohydrate called cellulose makes a plant’s cell walls. Proteins are made of monomers called amino acids. Proteins make up the muscles and structural tissue in a body, and they make enzymes which control chemical reactions. Proteins form peptide bonds between amino acids, which make up a polypeptide.
4. Fructose is component of sucrose, normal table sugar, along with glucose. Whereas glucose is able to immediately enter into glycolysis, fructose is not. Fructose is broken down via fructokinase into fructose- 1-phosphate. Fructose – 1-phospate then gets converted into DHAP+ glyceraldehyde via aldolase B. DHAP+ glyceraldehyde is used in glycolysis to produce pyruvate that goes into the citric acid cycle to produce ATP
The response to each carbohydrate was quantified when the respective carbohydrate was given alone in a drink or when given in combination with protein and fat in a test meal. The data demonstrate that (1) fructose ingestion resulted in significantly lower serum glucose and insulin responses than did sucrose or dextrose ingestion in all study groups, either when given alone or in the test meal; (2) although fructose ingestion always led to the least glycemic response compared with the other hexoses, the serum glucose response to fructose was increased the more glucose intolerant the subject; (3) urinary glucose excretion during the 3 h after carbohydrate ingestion was greatest after dextrose and least after fructose in all groups. In conclusion, fructose ingestion results in markedly lower serum glucose and insulin responses and less glycosuria than either dextrose or sucrose, both when given alone or as a constituent in a test
The type of sugar affects the rate of cellular respiration because each sugar is classified as either a monosaccharides, disaccharides or polysaccharides. The data from this experiment was collected by the amount of carbon dioxide produced from the type of sugar that was used. The data was then analyzed using a line graph. Data was also collected in class averages. There were three sugars in this experiment, glucose, lactose, and fructose. An example of a monosaccharides would be glucose and fructose. The slope for glucose should be about 283.07. The slope for fructose should be about 269.77. Second, an example of a disaccharides would be lactose. The slope for a disaccharide in this experiment should be about 67.055. The data shows that
The sucrose concentration in the solution was varied to 10%, 20%, 30%, 40% and 50% in order to examine the effect of varying sucrose concentration on the CO2 production of yeast cells.
Purpose Statement: To inform my audience of the effect sugar has on the human body.
Contrariwise, the results recorded as an outcome of the experiment did not support the hypothesis. The most carbon dioxide was produced for sucrose as it was doubled the amount produced in glucose. This should not have happened due to the fact that glucose is a monosaccharide that does not require any
The topic that I will be writing for the research paper is sugar and diet. I want explore more how does sugar play a role in our everyday diet. Growing up in my family, my mother has been always emphasize the importance of health. In the household, we do not store any unhealthy snacks or sugar added drinks, however, I do love sweets. I think sugar can bring people happiness, but i also understand overconsumption of sugar will also bring physical health problems. Therefore, I want to discover specifically on what is sugar exactly, how much sugar we consume everyday, and what can sugar do to our body.
My question is can you transform natural sucrose into glucose as you would unnatural sucrose? My variables. The independent variables are the bananas and apples, will the natural sugar affect the process. The dependent variable, will the “glucose” resemble the unnatural glucose. My hypothesis is that no, the natural sugar will not transform into glucose the way unnatural sugar.
Table Sugar is a compound. The white stuff we know as sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen. Sucrose is just a compound that is the component of cane or beet sugar. Sugar is a name for sweet, short-chain soluble carbohydrates, many of which are used in food.There are different types of sugar used in different sources.The table sugar is mostly used as food is sucrose. Sugar is used almost everywhere ! It is used in a lot of food items such as donuts, cupcakes, chocolate, coffee, tea, etc. Even though sugar is mainly used in food, there are some other uses of sugar too. Sugar can be used from fighting microscopic parasites to fighting grass stains. Sugar also has many other functions
It’s fair to say that we all have at least thought about not eating sugar anymore because it can be unhealthy at times and we don’t fully understand how our bodies digestive system works. Numerous questions swirl our brain as we take one single bite out of the stack of sticky- sweet pancakes or anything else sugar related.In this this paper, you will understand the different types of sugars, how the digestive system breaks down different sugars, and what too little or too much sugar can lead to in terms of health.
