Document Summary

Building blocks: protein long chains of aa, carbs long chain of monosaccharides, stored inside muscle and liver as glycogen, triglycerides 3 fatty acid + 1 glycerol, stored inside fatty (adipose) tissue. Glycolysis: glucose enters cell; either converted to g-6-p and used to produce. Atp or stored as glycogen: g-6-p pyruvate, pyruvate will either go through citric acid cycle or anaerobic pathway if o2 present citric acid. Citric acid cycle: sufficient o2 then this cycle functions properly, co2 diffuses into blood and leaves at the lungs. Metabolism of fats and amino acids: aa converted to either pyruvate or acetyl coa to enter glycolysis. Or cac: fat broken down into glycerol and fatty acids, glycerol glycolysis, fatty acids acetyl coa (cac) Fed state condition body is in after a meal high nutrients in blood. Recall: insulin is the hormone of the fed state secreted by beta cells in pancreas in response to high glucose in blood.
