Aim: The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that are directly absorbed into the bloodstream during digestion. Materials: 2% yeast

Carbohydrate and Diabetes Research NUR 115 AM The articles that I researched for this project were interesting and shed light on the relationship between carbohydrates and diabetes. Some of the information that I learned will be useful in my nursing career. Carbohydrates fill numerous roles in living things‚ such as the storage and transport of energy in the form of starch and glycogen etc. The basic carbohydrate units are called monosaccharides‚ such as glucose‚ galactose‚ and

substitutes; fats; free foods; combination foods; fast foods; and alcohol. Carbohydrate Counting When you eat a healthy meal or snack‚ it is usually a mixture of carbohydrate‚ pro- tein‚ and fat. However‚ your body changes carbohydrate into glucose faster than it changes protein and fat into glucose. It is the carbohydrate that makes your blood glucose level go up. In carbohydrate counting‚ you count foods that are mostly carbohydrate. These include starches (breads‚ cereals‚ pasta)‚ fruits and fruit

diet trend is the “Low Carbohydrate/High Protein” diet. To break it down simply proteins are needed to help the body to grow and repair while carbohydrates provide energy. Both are needed in order for a person to remain healthy‚ which is why fad diets that promote one over the other are harmful to our bodies. Fad diets such as the “low carb/high protein” diet tend to have one thing in common. They promote the exaggerated benefits of their program and show unrealistic results all while telling the

The structure and function of carbohydrates A carbohydrate is an organic molecule containing only Carbon‚ Hydrogen and Oxygen with the general formula Cn(H20)n. They are made up of individual molecules called monomers which are joined together by condensation reactions to make a longer chain called a polymer. Carbohydrates are categorised in to three main groups; monosaccharides‚ disaccharides and polysaccharides. Monosaccharides are single sugars and are sweet tasting soluble substances such

A study recently published in the San Jose Mercury News suggests the parents of obese children do not perceive their children as obese. An analysis of this study‚ its methods‚ and its findings is an important exercise in understanding the meaning and relevance of all research. The ability to read research critically and understand how it was generated allows us to identify possible design flaws or to realize the validity of its conclusions and make appropriate use of the data. The study was conducted

VI. Results and Discussion In this exercise‚ the goal was to produce acetylsalicylic acid through the organic synthesis from the reaction of salicylic acid to acetic anhydride‚ the starting materials. Instead of using acetic acid‚ acetic anhydride was used as solvent since the anhydride reacting with water to form acetic acid tends to drive the reaction to the right. It results from the elimination of a molecule of water from two molecules of acetic acid (see Fig. 11.2). Figure 11.3 below
