diabetes mellitus is caused when the body does not use insulin in a proper way. This issue is named insulin resistant. Insulin is essential to maintain glucose levels normal. Beta cells in pancreas are the responsible for the production of insulin‚ but eventually the production of insulin cannot keep up and not enough insulin is made to keep normal blood glucose levels. To control diabetes‚ a lifestyle change

Isolation and identification of an unknown bacterium Pillay‚ Esmerelda (209504371) School of Biochemistry‚ Genetics and Microbiology Department of Microbiology University of Kwa-zulu Natal 25 October 2010 ABSTRACT Different types of bacteria in various forms are found all around us‚ and it is a microbiologist’s job to be able to identify these bacteria. Using various staining techniques and physiological tests‚ an isolated bacterium can be identified. In this experiment‚ a single bacterial

Cellular respiration is defined as an enzyme mediated process in which organic compounds such as glucose is broken down into simpler products with the release of energy (Duka‚ Diaz and Villa‚ 2009). It is a series of metabolic processes and oxidation-reduction reactions. Oxidation of substrates‚ such as glucose‚ is a fundamental part of cellular respiration (Mader‚ 2009). As a catabolic process‚ it may or may not require the presence of oxygen. The process that requires oxygen is called aerobic

beings‚ without them we couldn’t survive. They act as catalysts that break down substances such as starch and convert them into different products such glucose‚ needed for cells to do their job within the body. Amylase in an enzyme that breaks down starch by breaking the long chains of polysaccharides into disaccharides‚ which is converted into glucose. In the human body there are several main sources of carbohydrates. Which are sucrose ( cane sugar) lactose (a disaccharide in milk) starches (present

Young Abstract This lab shows the use of salivary amylase with strong and weak starch mixtures to break down complex carbohydrates into simpler sugars. This lab was conducted to physically see the breakdown of carbohydrates into simpler sugars (glucose‚ fructose‚ galactose) using the salivary amylase enzyme. This is extremely important to all metabolic functions in the human digestive system. It is found that benedict’s solution‚ when heated makes a yellow-orange colour to indicate the simple sugars

Energy in context Introduction Digestion is the breakdown of large insoluble food molecules into smaller molecules so they can pass though the intestinal wall into the bloodstream and be transported throughout the body. There are seven different food groups in a balanced diet which should include Carbohydrate‚ fat‚ water‚ protein‚ fibre‚ vitamins and minerals. Although most foods contain these in some shape or form the foods that contain most of one type fall into that category‚ a chicken

color‚ which shows there is starch present. Noodles The liquid containing the noodles in it had turned to a black color‚ which shows there is starch present. Discussion: Starch or amylum is a carbohydrate consisting of a large number of glucose units joined by glycoside bonds. This starch is also found in green(leafy) plants as an energy store. Starches and sugars are the major carbohydrates or foods that produce energy for the body Conclusion: In conclusion the test was a success

soft. 6. Soap is formed by molecules with a "head" which likes water (hydrophilic) and a long chain which hates it (hydrophobic). 7. Lactose is the main complex sugar found in the milk. It’s a pretty big compound formed by two smaller components: glucose and galactose. Such a big compound cannot get through the intestinal wall and into the bloodstream‚ so we need "something" to break it into smaller pieces. This "something" is an enzime named lactase. The more milk and milk products we consume‚ the

triphosphate. There are three stages of cellular respiration-glycolysis‚ citric acid cycle‚ and electron transport chain. What is the role of glycolysis? Include the reactants and the products. Where does it occur? The role of glycolysis it to turn glucose molecule into energy by breaking it down in to two three carbon molecules. During this process two molecules of ATP‚ two molecules of pyruvic acid and two NADH molecules are produced. This process occurs in the ytoplasm of a cell‚ outside the mitochondrion
