Some people trying to lose weight have gone on the “Atkins
diet,” in which they eat mostly high-protein, low-carbohydrate
foods such as meat, cheese, and eggs. The amino acids in these
protein-rich diets, such as alanine, glycine, and serine, can be
converted to pyruvate by deamination (removal of the amino group).
Based on this scenario as well as your knowledge of cellular
respiration, how many ATP, NADH, and FADH2 molecules
will be generated from one molecule of alanine during the
mitochondrial matrix reactions?

A. two FADH2, three NADH, and two ATP

B. no FADH2, one NADH, and two ATP

C. one FADH2, four NADH, and one ATP

D. one FADH2, one NADH, and one ATP

E. two FADH2, six NADH, and two ATP
