1. what are the 2 main sources of amino acids?
diet and synthesis

2. describe the diet as an amino acid source
essential and non-essential amino acids
nitrogen/amine groups

3. describe synthesis as a source of amino acids
glucose
citric acid cycle carbons from other pathways

4. ___ concentrations are tightly controlled
amino acid

5. T or F:
there is an explicit long-term amino acid storage system
false
production of amino acids is dictaed by demands of synthesis since there is no long-term storage system

6. synthesis of amino acids is a steady state process. what does that mean?
the body is always producing amino acids
specific amino acids are produced as needed based on demands

7. describe the primary amino acid synthesis pathways. what are the 7 precursors?




glycolysis
3-phosphoglycerate
phosphoenolpyruvate
pyruvate


pentose phosphate pathway
ribose 5-phosphate
erythrose 6-phosphate


citric acid cycle
oxaloacetate
alpha-ketoglutarate
