CHO, Lipid, & A.A. metabolism Flashcards
Where does energy come from in the absorptive state
It comes from oxidizing nutrients entering the blood stream from the gut
—) immediate use or storage
What does each get turned into
- carbohydrates
- fatty acids
- proteins
Carbs —) monosaccharides
Fat —) Fatty acids
Proteins —) amino acids
Which goes to the blood which goes to the lymph
—) where does each go after entering either the blood or the lymph
- monosaccharides
- amino acids
- triglycerides (in what form)???
Monosaccharides —) blood —) liver (body)
Amino acids Proteins —) blood —) liver (body)
Fatty acids/triglycerides —) lymph —) adipose tissue and mammary tissue
Describe the pattern of the absorptive state for carnivores & omnivores and for ruminants
Carnivores and Omnivores
—) alternate periods of energy storage and use
Usually in absorptive state for about 12 hrs
Ruminants —) digestion is more continuous
Describe the pattern of the absorptive state for carnivores & omnivores and for ruminants
Carnivores and Omnivores
—) alternate periods of energy storage and use
Usually in absorptive state for about 12 hrs
Ruminants —) digestion is more continuous
What happens to nutrients in the post absorptive state
WHY?
Nutrients are mobilized from the bodies storage (from tissues)
To maintain glucose levels and for energy supply
What forms is energy stored as
Glycogen (glycogenesis) and fat
What organ is a key player in anabolic and catabolic states
The liver
Where are amino acids created and broken down
In the liver
Why is amino acid composition less important in ruminants ???
Because they have microbial proteins that can synthesize amino acids
What kind of amino acids does the liver create and modify
Non-essential amino acids
What is the main regulator of the absorptive phase
Insulin
What does each cell secrete, where do they come from
- alpha
- beta
- acinar
Alpha —) glucagon
Beta —) insulin
Acinar —) digestive enzymes
