Document Summary
Energy metabolism: how the body obtains and uses energy for food. Catabolism: breaking down body compounds, releases energy. Released during breakdown of glucose, fatty acids, and amino acids. Their negative charge makes them vulnerable to hydrolysis. Enzymes: facilitators of metabolic reactions coenzymes: organic. without coenzymes, an enzyme cannot function. not a protein. many are vitamins & minerals. Fats (triglycerides) - glycerol and fatty acids. Glycerol can be converted to glucose or pyruvate. Fatty acids to acetyl coa through fatty acid oxidation which releases hydrogens and electrons glycolysis. Monday, october 3, 2016 breaking down aa deamination (take of nitrogen group) of amino acids. points of entry include: Enter tca (krebs) cycle directly amino acids to glucose. Circular path: acetyl coa, oxaloacetate made primarily from pyruvate. Hydrogen atoms and their electrons: niacin and ribo avin. Electron transport chain captures energy as atp series of proteins. Inner membrane of mitochondria electrons massed to the next carrier.
