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

what biological compounds we were dealing with as we had no idea what each substance was and all samples looked the same therefore we had to carry out a series of tests to figure out what structures they were made of. Some simple sugars‚ including glucose‚ can be made to reduce blue copper sulphate to red copper oxide. This reaction can be used as a test for some sugars. Copper sulphate is mixed with other chemicals to be used as Benedict’s solution which is used in the test. This was the test for

For dancers‚ a balanced food group diet is required involving diary‚ protein‚ grains‚ fruit/vegetables and fats. Through following this structured diet‚ a dancer will obtain the correct amount of caloric intake. The estimated calories a female dancer should digest through intense training are 45-50 calories per kilogram of body weight. Following this requirement will help prevent injury as obtaining a low caloric intake affects performance‚ growth and health. The benefit of protein for a dancer is

Biology coursework: Substrate specificity in yeast AIM: To find out which substrate (glucose‚ starch‚ maltose‚ sucrose or lactose)‚ does yeast‚ the organism containing the enzyme‚ breaks down the quickest. Introduction: Usually‚ every enzyme has a specific substrate that is what we call the “lock and key” theory. We can try the reaction of an enzyme with different substrates and this enzyme will just work well with one of those substrates. One type of reaction catalyzed by enzymes is anaerobic respiration

were able to observe and record starch Hydrolysis. (Table 1) * In order to test carbohydrate catabolism under anaerobic conditions we tested cultures of Pseudomonas aerugenosa‚ Escherichia coli‚ and Alcaligenes faecalis in tubes containing a glucose medium. After inoculating each tube with each of the bacteria 5mm of mineral oil was poured into one of the tubes containing bacteria to observe anaerobic respiration and while one remained without mineral oil. (Table 2) * We then observed protein

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

how starch and cellulose are treated to allow them to be used by the yeast? One potential ethanol feedstock is starch. Starch molecules are made up of long chains of glucose molecules. Thus‚ starchy materials can also be fermented after breaking starch molecules into simple glucose molecules. Examples of starchy materials commonly used around the world for ethanol production include cereal grains‚ potato‚ sweet potato‚ and cassava. A great amount of ethanol fuel is currently produced by starch

microscope‚ chloroplasts (green organelles) in Elodea tend to bound to the cell wall in pond water‚ spread all over the cell in distilled water‚ pull away from cell wall in 20% NaCl. In our last experiment‚ we use a dialysis bag that contains 30% glucose and starch solution then place into a beaker of water and iodine solution. We then remove the bag out of the beaker‚ and use two test tube which label BAG‚ BEAKER to perform a Benedict’s test. We place solution in the bag in the BAG tube‚ and solution

Muslims‚ but also to food producers‚ by means of increased market acceptance of their products. In food production‚ sugars are widely used as it could make the food and beverage taste sweet and delicious. There are many types of sugars such as glucose‚ fructose‚ lactose and maltose. A problem occurs as those sugars might transform to an alcohol named ethanol (or ethyl alcohol) by natural fermentation process which is not performed by enzymes. According to scientific review‚ both natural and manufactured

Health benefits of dates fruit are uncountable. Intestinal Disorders: The nicotinic content that is present in the dates is said to be beneficial for curing any kinds of intestinal disorders. Continuous intake of dates helps to maintain a check on the growth of the pathological organisms and thus‚ helps in the rise of friendly bacteria in the intestines. Constipation: Date is termed to be a laxative food. This is the reason that dates are beneficial for people suffering from constipation.
