A lipoyl group of dihydrolipoyl transacetylase (E2) is covalently attached to:

Which of the following cannot be used as a precursor for gluconeogenesis in the human liver?

The reactions of glycolysis and gluconeogenesis are regulated through the conversion of fructose-6-phosphate and fructose-1,6-bisphosphate, and vice versa. The following statements about this regulation are correct EXCEPT

Adding 2,4-dinitrophenol to an actively respiring cell tissue culture would likely result in all of the following, EXCEPT

What phosphoryl donor is used in the reaction of converting oxaloacetate to phosphoenolpyruvate?

What enzyme catalyzes the anaplerotic reaction of oxaloacetate formation from pyruvate?

The liver isozyme of pyruvate kinase can be inhibited by covalent modification when PKA is stimulated by increased cAMP concentration. However, the muscle isozyme is not affected by covalent modification. As a result,

What enzyme catalyzes the anaplerotic reaction of oxaloacetate formation from pyruvate?

Cytochromes are:

Which complex mediates the transfer of electrons from a membrane-soluble carrier to a water-soluble carrier in the ETC?
