Some People Trying to Lose Weight Have Gone on the Atkins

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? Hint: Only consider the reactions from the point at which the alanine carbons enter cellular respiration.

A) 1 FADH₂, 4 NADH, and 1 ATP
B) 0 FADH₂, 1 NADH, and 2 ATP
C) 2 FADH₂, 3 NADH, and 2 ATP
D) 2 FADH₂, 6 NADH, and 2 ATP
E) 1 FADH₂, 1 NADH, and 1 ATP
