Absorptive Pathways
fates of Carbohydrates, Fats, Proteins
Question | Answer |
---|---|
When is the Absorptive State? | nutrients entering blood from the GI tract |
What is the Metabolic Goal of the Absorptive State? | IMMDIATE Energy needs & STORAGE of Excess Calories |
What is the fate of most Glucose during the Absorptive State? | CO2 + H2O + ATP (immediate) |
What would be the fate of Glucose going to the Liver/Muscle? | Glycogen (stored) |
What would be the fate of Glucose going to the Liver? | 3 FA & 1 Glycerol --> Triglycerols --> Adipose |
What is the fate of most Triglycerols during the Absorptive State? | FA & Glycerols --> CO2 + H2O + ATP (rarely used immediately) |
Why is the ATP formed by dietary fats rarely used immediately? | usually still plenty of Glucose readily available |
What is the fate of most dietary Proteins ? | Amino Acids --> Protein Synthesis --> enzymes, protein, anti-bodies |
What is the fate of the dietary Proteins that go to the Liver/Muscle? | Amino Acid Pool |
What is the fate of the dietary Proteins? | AA--> Damination --> Keto Acid + Ammonia = Urea |
