Glycogen phosphorylase-a catalyzes the nucleophilic attack on the glycosidic bonds of the glycogen particle in what is known as a phosphorolysis reaction. Which bond(s) is(are) cleaved? What is the product of one cleavage reaction?

In glycolysis, the reaction sequence between dihydroxyacetone phosphate and 3-phosphoglycerate involves all of the following EXCEPT:

Crib death of infants when fasting (i.e., when sleeping and not eating – therefore a low blood glucose condition) is also known as sudden infant death syndrome (SIDS). SIDS was often blamed on lack of proper care by the parents of the child. It is now known that a significant number of SIDS cases are caused by a genetic defect in the gene that codes for fatty acyl-CoA dehydrogenase, the enzyme that catalyzes the first step in fatty acid β-oxidation (see question 34 for this reaction). If this enzyme is defective, energy from fatty acids is not available and gluconeogenesis is inhibited resulting in severe and life-threatening hypoglycemia (low blood glucose). Why the hypoglycemia?

The electron transport chain (ETC) is comprised of membrane-embedded enzymes that catalyze electron transfers. What are the MOBILE electron carriers associated with the ETC?

In an experimental system for the study of the electron transport chain, electrons can be supplied by adding ascorbate as an artificial electron donor. When using ascorbate in these experiments it is necessary to include an electron acceptor such as TMPD (an intermediate electron acceptor) that accepts electrons from ascorbate and then donates electrons to cytochrome c. In this experimental system it would be possible to transfer electrons directly to which complex?

The stoichiometry of gluconeogenesis is the following: In gluconeogenesis, what enzyme(s) require GTP as a substrate?

At the equilibrium wage rate, how many fast-food restaurant workers are employed?

Which of the following is the most critical determinant of market power?
