brief outline of glucose metabolism
glucose > glucose 6 phosphate > [glycolysis] > pyruvate > [PDH complex] > acetyl CoA > [citric acid cycle] > energy
What happens to amino acids when energy is needed?
1. Amino acids > [oxidation] > ATP
2. Amino acids > [gluconeogenesis] > glucose > ATP
Where do amino acids get converted into glucose?
liver
What happens to amino acids when protein and energy needs have been met?
Amino acids get converted to fatty acids and stored in adipose tissue
What is the intermediate of the citric acid cycle that ties into gluconeogenesis?
oxaloacetate
Amino acid + α-keto acid -->
glutamate + α-keto acid
water + glutamate -->
ammonia + α-ketoglutarate
What happens to ammonia?
ammonia > urea cycle > urea > excreted in urine
order the lipoproteins from lowest to highest density
chylomicron, VLDL, IDL, LDL, HDL
