Which of the following compounds is a key intermediate in gluconeogenesis from lactate, pyruvate, alanine, and glutamic acid?

Which is the only amino acid that does not have a resonance isomer (i.e. enantiomer with L and D forms)

The substrate for the committed step in glycolysis is:

Enzyme X has a Km for substrate A which is twice as large as its Km for substrate B.  If the enzyme is added to a solution containing equal, but low concentrations of A and B, and Vmax for A and B are equal: (Remember – the lower the Km, the higher the affinity)

The genetic code is said to be redundant or degenerate. This means that:
