The reason for the net ATP production being 2 less than the gross production during a β-oxidation process has to be determined. Concept introduction: The total ATP molecules produced by the oxidation of a fatty acid molecule is the sum of all the ATP molecules produced from the metabolic products, acetyl CoA, FADH 2 and NADH. Acetyl CoA generated by the β-oxidation enters the citric acid cycle in the mitochondria where it undergoes oxidation to generate FADH 2 and NADH. The FADH 2 and NADH generated by both β-oxidation and the citric acid cycle are utilized by the mitochondrial electron transport chain to generate ATP molecules. These ATP molecules act as units of energy.

Question 15 Glycogen storage disease type I (GSD I) or von Gierke's disease, is the most common of the glycogen storage diseases. This genetic disease results from deficiency of the enzyme glucose-6-phosphatase. The metabolic outcomes of GSD I are likely to include: O Low blood glucose, increased blood pH, increased glycogen storage in liver and kidneys O High blood glucose, decreased blood pH, decreased glycogen storage in liver and kidneys O Low blood glucose, increased blood pH, decreased glycogen storage in liver and kidneys O Low blood glucose, decreased blood pH, decreased glycogen storage in liver and kidneys High blood glucose, decreased blood pH, increased glycogen storage in liver and kidneys O High blood glucose, increased blood pH, increased glycogen storage in liver and kidneys O High blood glucose, increased blood pH, decreased glycogen storage in liver and kidneys O Low blood glucose, decreased blood pH, increased glycogen storage in liver and kidneys

15.7) Determine whether each of the following changes is an oxidation or reduction. a) gain of electrons reduction b) loss of electrons oxidation c) Fe²+ to Fe³+ oxidation d) NADH to NAD+ oxidation lost bond to hydrogen atom e) FAD to FADH₂ reduction gained bond to hydrogen atom f) CH4 to CO₂ oxidation gained bonds to oxygen atoms and lost bonds to hydrogen atoms g) NAD+ to NADH reduction gained bond to hydrogen atom EXPLANATION: A useful mnemonic to differentiate oxidation and reduction is the term "OILRIG" (Oxidation is the Loss of electrons; Reduction is the Gain of electrons). It is possible to identify redox reactions for inorganic compounds by inspecting the chemical equation and determining if electrons are transferred from one species to another. If the charge of an atom or ion in a reactant was increased (toward positive) in the conversion of reactants to products, an oxidation occurred. If the charge of an atom or ion in a reactant was decreased (toward negative) in the…
