    Experiment 14. Dehydrogenase in yeast During respiration‚ hydrogen atoms are removed from glucose molecules by enzymes called dehydrogenases and passed to various chemicals called hydrogen acceptors. As the hydrogen atoms pass from one hydrogen acceptor to another‚ energy is made available for chemical reactions in the cell. In this way‚ substances such as glucose provide energy for vital reactions in living organisms. In this experiment‚ a dye called methylene blue acts as an artificial hydrogen

    respiration is respiration without oxygen; the process uses a respiratory electron transport chain but does not use oxygen as the electron acceptors. Cells that use it Aerobic respiration occurs in most cells. Anaerobic respiration occurs in bacteria‚ yeasts‚ some prokaryotes‚ erythrocytes (red blood cells)‚ and in muscle cells. Production of lactic acid Does not produce lactic acid Produces lactic acid (in lactic acid fermentation but not in alcoholic fermentation) Amount of energy released High (36-38

    linked in order to provide you with energy from the food you eat. To start off with we will need to define photosynthesis and respiration. Photosynthesis is a process in which carbon dioxide‚ water‚ and certain inorganic salts are converted into carbohydrates by green plants‚ algae and certain bacteria using energy from the sun and chlorophyll (dictionary.com). Respiration is all of the physical and chemical processes in an organism by which oxygen is conveyed to tissues‚ cells and the oxidation products

    Fermentation of a Carbohydrate: Ethanol from Sucrose Abstract The purpose of this lab was to demonstrate the fermentation process of ethanol from the substrate sucrose. To make ethanol from sucrose two enzymes invertase and zymase were used. Vacuum filtration and fractional distillation were performed to get a more concentrated solution. The density of ethanol was .825 g/mL with a percent composition of 85% pure

The phytochemical captin present in the fruit is used in medication to treat heart problems. Dragon fruits have no complex carbohydrate. The carbohydrate source comes from fructose and glucose‚ which are the main sugar component in the fruits (Liaotrakoon‚ 2013). Besides‚ they also contain other nutrients such as polyunsaturated (good) fatty acids‚ carotene‚ and protein. Lycopene pigment
