Carbohydrate Fermentation Testing Questions A. What is fermentation? It is a metabolic process that allows the production of ATP without need for oxygen B. Why is it important not to incubate the fermentation tubes beyond 24 hours? You may not get accurate results. Although sugar is the primary nutrient used‚ when a microbe runs out of it‚ protein or other nutrients will be attacked This causes changes in the color of the medium because of the pH indicator added to detect acid production. When proteins

thing to eat before a game? What’s the best thing to eat before a game? Before a game you want carbohydates(excuse the spelling) and minerals.Carbohydrates are a source of energy.One of the highest sources of carbrohydates is Pastas.Pastas store carbohydrates in you stomach for about 3 hours.In wich you could use for a soccer game.Gatorade would also be good but I’mn ot a 100% on that one. You’ve probaly heard of the cross-over from basketball but Soccer Maniac’s Site has kind of "developed" a soccer

Analysis: Lab 1 Identifying Carbohydrates There were many ranges of color changes in the Benedicts test and Iodine stain. For the Benedicts test‚ this oxidation/reduction response changes the arrangement of the reducing sugar creating a colored precipitate. The change in color is correlated to the first concentration of the reducing sugar. For the iodine test‚ the three dimensional structure of various polysaccharides permits them to react with the iodine stain to produce a certain color. As far

Through this investigation we found no effect in carbohydrate mouth rinsing on exercise performance. On the contrary to our hypothesis‚ there was no significant difference in distance cycled between those who carbohydrate mouth rinsed and the control (Fig. 1.). In addition‚ we also found that there was no significant difference in HR throughout the entire investigation between treatment groups (Fig. 2.). These exercise performance results is inconsistent with those results obtained by Carter et

D_____ J_____ CARBOHYDRATES LAB May 22‚ 2013 Pre-lab Questions 1. The water in test tube No. 1 is a negative control. No reaction is expected to occur because water is not a carbohydrate. Reaction by a negative control is evidence of contamination. 2. The color changes expected for positive test results are Benedict’s test: orange to brick red Tollen’s test: metallic silver Starch iodine test: blue-black 3. Identify each of the samples in Part 1 as monosaccharide

Purpose: The purpose of this lab was to see how the changes in exercise intensity affect the rate of metabolism within the body. Methods: In this lab‚ indirect calorimetry was used to measure metabolic rate by calculating caloric expenditure by the measurements of oxygen consumption. The variables measured were the fraction of oxygen expired‚ the fraction of carbon dioxide expired‚ and the total volume of air inspired. This experiment required the participation of two volunteers. First‚ the variables

The importance of carbohydrates in living organisms Carbohydrates contain carbon‚ hydrogen and oxygen in the ratio of 1.2.1.. There are many different types of carbohydrate‚ all of which are useful to living organisms. The most important carbohydrate is probable glucose. Glucose is a monosaccharide and is the monomer unit which makes up more complex polysaccharides. Two glucose molecules can be joined in a condensation reaction‚ whereby water is removed‚ for example to produce maltose‚ a disaccharide

T2:BIOCHEMISTRY AND ANALYSIS:DETECTION OF FATS‚PROTEINS AND CARBOHYDRATES OBJECTIVE The main purpose of the experiment is to understand some general tests that detect fats‚proteins and carbohydrates in foods. INTRODUCTION Carbohydrates are also known as sacharides. There are 4 main groups of carbohydrates‚which are monosaccharides‚ disaccharides‚ oligosaccharides and polysaccharides. Carbohydrates play an important role in living organism as it is the energy storage‚ and it also plays

result in Benedict’s test as the colour of solution change from blue to brick-red and there is brick-red precipitate. Starch give positive result in Iodine test as the colour of solution change from yellow to dark blue. Glucose is the simplest carbohydrates that are monosaccharide or simple sugar. Starch consisting of a large number of glucose units joined together by glycosidic linkage and known as polysaccharide‚ that is polymers of sugar. Saliva that contains salivary amylase enzyme‚ which breaks

We have four important macromolecules; carbohydrates‚ lipids‚ proteins‚ and nucleic acids. From these four‚ the macromolecule I chose for this assignment was carbohydrate. Carbohydrates branch off into three main categories; monosaccharides‚ disaccharides‚ and polysaccharides. I decided to focus on disaccharides‚ specifically sucrose. Sucrose is more commonly known as table sugar. It has a chemical formula of C12H22O11. It is physically described as a white‚ odorless (although when heated‚ it may
