Glucose Oxidase and Its Various Uses Aaron Truong Since glucose oxidase has an end product called hydrogen peroxide, which is a harmful substance to bacteria, it can be used to fight bacteria, or sterilize objects (can have various uses such as in hand sanitizers, toothpaste, soap, etc), not just biosensors. Another key part in the reaction would be C6H12O6, or glucose. Glucose oxidase can be applied to diabetics as mentioned earlier, as biosensors work by "keeping track of the...

Carbohydrates: Glucose and Taste Threshold

Solubility of Carbohydrates , Glucose , Galactose and Lactose . Objective : To determine the relative solubility of glucose , galactose and lactose by measuring their saturation point at the same constant temperature. Principle : With 10g distilled water contained in a beaker , then add small quantities of the carbohydrate being test at a time with constant stirring until no more can dissolve , saturation point is represented at r.t.p.. Test the carbohydrates , glucose , galactose and lactose ...

Glucose and Cellular Respiration

evolved than MgSO₄. In the second set-up, six Smith fermentation tubes were used each containing different 15mL solution (starch, lactose, sucrose, glucose, fructose or distilled H₂O). the tubes were then added with 15 mL distilled H2O and 15 mL 10% yeast suspension. Here, results show that fructose had the highest rate of respiration followed by glucose, sucrose, lactose, starch and H₂O. Thus, simpler substrate would mean higher rate of respiration. INTRODUCTION We all need life to survive. Life...

Glucose and Identifying Nutrients Gizmo

tests with the Identifying Nutrients Gizmo™. 1. Below the Food samples label, drag tube A into the Food sample holder. Below the Benedict test, click the Test button. The Benedict test is a test for monosaccharides; simple sugars like glucose or fructose (fruit sugar). In contact with monosaccharides, the Benedict solution turns from blue to pink. Does Sample A contain monosaccharides? _________ Note: Disaccharides such as sucrose (table sugar) and lactose (milk sugar)...

DETERMINING THE GLUCOSE CONTENT OF AND ORANGE USING GOD-PAP ASSAY Every fruit has a sweet taste only that some are sweeter than others. The sweetness of most fruits come from its sugar content and these sugars that the fruits contain are known as invert sugars. In this experiment, an orange was used. An orange which is an excellent source of vitamin C gets its sweetness from natural sugars which are sucrose, glucose and fructose (livestrong.com). In this experiment the concentration of glucose in an orange...

The Effect of Glucose Concentration on Anaerobic Respiration in Yeast

THE EFFECT OF GLUCOSE CONCENTRATION ON ANAEROBIC RESPIRATION IN YEAST INTRODUCTION: Yeast, also known as a saccharomyces cerevisiae, is single celled eukaryotic cells that are in the kingdom fungi and are unicellular organisms which normally reproduce asexually by budding at a very high rate. Scientists quite often decide to work with yeast because of its features fast growing rate and the fact that yeast's DNA can be easily manipulated. Some types of yeast can be found naturally on plant or in...

What Factors Influence the Body's Use of Glucose During Physical Activity? How?

of glucose during physical activity? How? The factors that influence the body’s use of glucose during physical activity are: diet, activity intensity level, and activity duration. (Whitney and Rolfes 466-468) First of all you must have a carbohydrate rich diet in order to store glycogen. Abundant glycogen stores enables people to perform physical activity longer at higher intensity. Glucose provided by carbohydrates (Whitney and Rolfes 466-468) Intensity of activity affects glucose use...
