Document Summary
Pyruvate: when body needs energy quickly sprinting. 2-carbon bonds with coa making = acetyl coa: removed carbon is converted to co2 which is removed through exhaling. Glycerol to pyruvate (hydrogens released to etc: can be converted to, pyruvate, making glucose, making acetyl coa. 2- carbon compounds combine with coa to make acetyl coa. Amino acids: deamination: loss of nitrogen containing amino group, must be deaminated before entering metabolic pathways, pathways, can be converted to pyruvate provide glucose, can directly enter the tce cycle (in form of other compounds besides acetyl. If atp is high, acetyl coa converted to fat and stored: generate atp. If atp is low, acetyl coa proceeds through tce cycle. Tca cycle (hydrogens released to etc: tca cycle is circular because, oxaloacetate is needed in the first step of tca and is synthesized in the last step in tca, oxaloacetate. Feasting-excess energy: carbs and proteins oxidized, fat is stored not oxidized.
