DEGREE IN NUTRITION CLINICAL BIOCHEMISTRY WORK SHEET No. 2 "Metabolic Interrelations II" OBJECTIVE By working out the form below you will understand how they relate to the organs responsible for the major metabolic pathways in the body and how involved each of the components in fast food cycle up to eating disorders such as protein calorie malnutrition. BACKGROUND For human beings, as well as many other agencies, represent the food source that can meet immediate energy needs, while becoming a reserve of nutrients and energy that cells of different tissues can be used during periods of fasting or restriction of exogenous nutrients.The metabolism, defined as the set of reactions that provide a continuous supply of substrates for the maintenance of life, including catabolic and anabolic processes. Catabolic pathways in the energy is released, part of which is transformed into adenosine triphosphate (ATP) and collected in small nucleotides (NADH, NADPH and FADH2). Anabolic reactions require an energy intake that usually is provided by the hydrolysis of ATP, a molecule that is universal carrier of metabolic energy and reducing power is also necessary, provided by the reduced nucleotide. Both the anabolic and catabolic pathways occur in three levels. Ski Shores At level 1, the interconversion occurs between the complex macromolecules (proteins, nucleic acids, polysaccharides and lipids) and single molecules, monomer (amino acids, nucleotides, sugars, fatty acids and glycerol).At level 2 takes place interconversion of monomers and simple organic compounds (pyruvate and acetilCoA). Finally, at Level 3, is carried out the degradation of these metabolic intermediates to inorganic compounds (CO2, H2O and NH3) or use of these precursors for the synthesis of different biomolecules. ACTIVITIES 1. In this first point, you should make a concept map involves the following concepts: blood transport, hormones, oxygen, BLOOD VESSELS, BLOOD, NUTRIENTS, WASTE, arteries, veins, NUTRITION. 2.From the following Internet address http://ibmc.umh.es/biorom/contenido/UCM/texto/int-metab-1.pdf done reading the article and summarize it that is marked in an overview where to place the p major ointments. 3. Observe carefully the following image, try to find a relationship between the organs and systems that occur in the cycle, a process called metabolic interaction, idea a way to explain this process to your classmates.You can select a short, making a story, a summary table, or what you even think, this activity exhibited in the classroom. 4. Finally read carefully the following, there is no physiological division for the fast food cycle, but it could be analyzed from three perspectives: State of good nutrition meet dietary energy requirements. Fasting state early and late fasting state. Which of these three hypothetical states you would like to know more Make a research on the Internet or specialized books to learn more about these processes and illustrated by a drawing the metabolic pathway that occurs in the state you selected. CONCLUSION Make a concept map where I showed the main ideas of this file, remember that you should try to include everything you read or researched and that your mind can be more important.
