Match the amino acids with their metabolic classification: Phenylalanine | Glucogenic and Ketogenic, Aspartate | Citric acid cycle, Leucine | Glucogenic, Alanine | Ketogenic.
Understand the Problem
The question is asking us to categorize amino acids based on their metabolic classification, specifically identifying whether they are glucogenic or ketogenic, or their role in the citric acid cycle.
Answer
Phenylalanine: Glucogenic and Ketogenic, Aspartate: Citric acid cycle, Leucine: Ketogenic, Alanine: Glucogenic.
Phenylalanine is both glucogenic and ketogenic, Aspartate enters the citric acid cycle, Leucine is exclusively ketogenic, and Alanine is glucogenic.
Answer for screen readers
Phenylalanine is both glucogenic and ketogenic, Aspartate enters the citric acid cycle, Leucine is exclusively ketogenic, and Alanine is glucogenic.
More Information
Phenylalanine is unique as it can be converted to both glucose and ketone bodies. Aspartate plays a crucial role in the citric acid cycle, while alanine is important for gluconeogenesis.
Tips
A common mistake is to confuse glucogenic and ketogenic classifications. Remember that leucine and lysine are strictly ketogenic, while others can fall into both categories.
