Metabolism Flashcards
Long term regulator of appetite
Lepton and insulin. Inform brain of how much apipose in body.
Short term regulators of appetite
Peptides ghrelin, peptide y y and cholecystokinin
Bad cholesterol
LDL
Good cholesterol
Hdl. Cholesterol being removed from arteries and transported to the liver for disposal
Products of glycolysis
2 pyruvic acid. 2 nadh . 2atp. 2h
Product of kreps cycle
2 atp. 8 nadh. 8 h. 2fadh. 6 co2
Products of mitochondrial electron transport
34 atp
What happens during aerobic respiration
Pyruvic acid enter the mitochondria and is oxidized.
2 principle steps- matrix reaction and membrane reactions
What happens during anaerobic fermentation
No oxygen. Cells can only generate atp through glycolysis. Nadh donates electrons to pyruvic acid reducing it to lactic acid and regenerating nad
What is the first step in using amino acids as fuel?
Deamination of them ( removal of amine group)
Glycogenesis
The conversion of glucose to glycogen for storage in the liver by insulin
Glycogenolysis
Glycogen broken down into glucose. Stimulated by glycogen and epinephrine.
Absorptive state
Fed. About 4 house during and after a meal. Nutrients are being absorbed.
Post absorptive state
Fasting. Prevails in the late morning , overnight. Stomach and intestines are empty
Bmr
Basal metabolic rate- a standard of comparison that minimizes the effects of activity, feeding and hormone levels.
