- Copper is a cofactor in several enzymes, including lysyl oxidase and superoxide dismutase.Ceruloplasmin, a deep-blue glycoprotein, is the principal copper-containing protein in blood. It isused to transport Cu2+ and maintain appropriate levels of Cu2+ in the body’s tissues.Ceruloplasmin also catalyzes the oxidation of Fe2+ to Fe3+, an important reaction in ironmetabolism. Because the metal is widely found in foods, copper deficiency is rare in humans.Deficiency symptoms include anemia, leukopenia (reduction in blood levels of white blood cells),bone defects, and weakened arterial walls. The body is partially protected from exposure toexcessive copper (and several other metals) by metallothionein, a small, metal-binding protein thatpossesses a large proportion of cysteine residues. Certain metals (most notably zinc and cadmium)induce the synthesis of metallothionein in the intestine and liver.In Menkes syndrome intestinal absorption of copper is defective.

- phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate and represents the key control point in mammalian glycolysis. The enzyme is a homotetramer that is inhibited by ATP binding, activated by AMP binding, negatively regulated by phosphorylation, and competitively inhibited by 2,5-anhydro-D-glucitol-1,6-diphosphate. (a) Would you expect a plot of the initial rate of fructose 1,6-bisphosphate formation as a function of substrate concentration to show a sigmoidal or hyperbolic curve? (b) How would each of the regulators above affect the dynamics of the T state to R state equilibrium of phosphofructokinase? Briefly explain your reasoning. (c) If it were possible to isolate phosphofructokinase monomers in an active form, how would you expect the kinetics in (a) to be affected? How would the rate of the reaction be affected by ATP, AMP, and 2,5-anhydro-D-glucitol-1,6-diphosphate?

- Although both hexokinase and phosphofructokinase catalyze irreversible steps in glycolysis and the hexokinase-catalyzed step is first, phosphofructokinase is nonetheless the pacemaker of glycolysis. What does this information tell you about the fate of the glucose 6-phosphate formed by hexokinase? Glucose 6-phosphate must be unstable and release its phosphoryl group over time. Glucose 6-phosphate must be utilized by other metabolic pathways. Glucose 6-phosphate must allosterically inhibit phosphofructokinase, but not hexokinase. Glucose 6-phosphate must be wasted when it is produced in excess.arrow_forwardWhich of the following glycolytic enzymes catalyzes the conversion of fructose-1,6-bisphosphate into the two product molecules dihydroxyacetone phosphate, and glyceraldehyde-3-phosphate? phosphoglycerate kinase pyruvate kinase malate dehydrogenase aldolase phosphofructokinasearrow_forwardThe coenzyme NAD+ is required for which glycolytic reaction shown below?
