(Figure 3‚ http://4.bp.blogspot.com) An example of how enzymes work within the body is the breakdown of fructose. Energy obtained from carbohydrates goes through a process called glycolysis. Glycolysis a series of biochemical reactions in which one glucose molecule is oxidized into two pyruvic acid molecules and a small amount of adenosine triphosphate (ATP). Generation of high energy molecules are used as cellular energy sources in aerobic and anaerobic respiration. The products formed through glycolysis

like non-cancer cells‚ utilize glucose as a primary energy source. Not only do cancer cells utilize glucose‚ but they take up the molecule in large quantities. This was explained decades ago by Otto Warburg‚ resulting in what is now referred to as the Warburg Effect1. The Warburg Effect explains how cancer cells alter their glucose metabolism to accommodate the rapid and uncontrolled division they undergo. In both cancer and non-cancer cells usually take up glucose from the environment‚ and it

UNKNOWN LAB REPORT UNKNOWN NUMBER 54 Ron Williams 7-28-05 Bio 205 Prof. Curlee Fall 2005 Purpose There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory

Intro: Carbohydrate‚ any of a large group of compounds in which hydrogen and oxygen‚ in the proportions in which they exist in water‚ are combined with carbon; the formula of most of these compounds may be expressed as Cn(H2O)n. Structurally‚ however‚ these compounds are not hydrates of carbon‚ as the formula would seem to indicate. Carbohydrates‚ as a class‚ are the most abundant organic compounds found in nature. They are produced by green plants and by bacteria using the process known as photosynthesis

composed of an even number of carbon atoms in a carboxyl group. Droplets of triacylglycerol molecules are stored in the cytoplasm of many cells. (Alberts‚ 2009) Polysaccharides is known as the high molecular weight compound form of simple sugar glucose that plants and animal store. Within plant cells‚ the storage consists of starch connected together by glycosidic bonds. A larger polymer in terms of molecular weight is glycogen. Through the iodine test‚ we are able to distinguish the presence of

should be negative and is not a protein. In the second experiment to test for glucose with the Benedict reagent sugar should be positive for glucose. Starch mixed with the Benedict reagent is probably positive for glucose because it is a polysaccharide. Onion juice mixed with Benedict reagent is probably positive for glucose because it is a fructose. Distilled water with Benedict reagent should be negative for glucose.

microorganism #17. Kliger’s Iron Agar slants also contains a pH indicator‚ phenol red‚ which can be used to test the presence of fermentation. If there is a glucose or lactose fermentation‚ the acid will be produced‚ and the color will change from red to yellow. If there is only glucose fermentation‚ the slant will have a yellow butt. If there are both glucose and lactose fermentation‚ there will be a yellow slant and butt. Kliger’s Iron Agar slants is also used to check the presence of hydrogen sulfide. If

(Wolfe‚ 2000) Importance of Aldolase B Enzyme -Glucose and fructose are the components that make up sugar (sucrose). -In order to make ATP (energy)‚ glucose and fructose need to go through glycolysis and enter the Krebs cycle. -Fructose needs enzymes to break it down further‚ before it can enter the glycolysis process. -Initially‚ fructose is
