Question

General Biology Chapter 6 Cellular Respiration Exercise For the Following questions, answer each thoroughly and sketch the parts of the Cell and/or Mitochondrion to illustrate your answer. 1. Triglycerides can be broken down by hydrolysis reactions to glycerol and fatty acid chains in the digestive tract. Glycerol is easily converted to 1 phosphoglyceraldehyde also known as PGAL Using your knowledge about how aerobic cellular respiration functions, explain how from this original glycerol molecule how many ATP's are formed in this process. Make sure you include explanations where each ATP is made. Fatty acid chains after subjected to degradative enzymes in the intestines are hydrolyzed (hydrolysis) into 2 Carbon acetic acid fragments (Each fragment becomes an acetyl Co-A molecule). What stage of cellular respiration will this product of lipolysis enter? How many ATP can one fragment produce in cellular respiration 2. 3. Calculate the number of ATP harvested from complete oxidation (breakdown) of a 18 carbon fatty acid? Use the information in the above question to help you Cyanide is a compound that is an irreversible inhibitor on cytochrome oxidase which prevents electrons being passed to oxygen from the last protein complex in the electron transport chain. How does this specifically cause ATP production to stop and would this cause death in a multi- cellular organism? Why or why not? 4. Physicians in the 1940's prescribed low doses of a chemical called DNP (dinitrophenol) to help patients lose weight. This practice was abandoned after several patients died after taking DNP. A hydrophobic DNP binds to Hydrogen ions in the mitochondrion inner membrane space causing the Hydrogen ions to move easily across the phospholipid bilayer. Would this stop ATP production? Why or why not? How would this cause death? 5. Glycolysis is a process that is reversible, meaning that any product that is being formed can easily go in the opposite direction and causes a sugar to "rebuild" itself. Once the end product of glycolysis moves into the mitochondrion, the products cannot leave the mitochondrion and enter glycolysis again. Amino acids, depending on the type, can be broken down into the following products: pyruvate, acetyl Co A, alph ketoglutarate and others. For each of those products, indicate where they would enter into the process of cellular respiration. Can any of those products form a glucose molecule, in other words, can any of the amino acids become a glucose in our cells, explain. 6.
