Document Summary
Brown fat keeps you warm independent of its insulating properties. Help people lose weight but killed them. H+ flows down its gradient (bypasses atp synthase) Mitochondria tries to make a lot of atp since it"s using it up to power other functions breaks down glucose and fat trying to make proton gradient but no atp being made!!!!! Energy stored in h+ gradient is stored as heat you"re cooking yourself! Glycolysis glucose pyruvate (o2 present) pyruvate oxidation citric acid cycle. Electron transport/atp synthesis co2 + h2o. Without o2 to accept electrons, pyruvate cannot be oxidized further. +o2: nadh converted back to nad+ in ets glycolysis and krebs cycle continue. O2 (not available or anaerobic organism): all nad+ will eventually be consumed glycolysis stops! Some aerobic organisms in absence of o2 (brewer"s yeast) Acetaldehyde ethanol is a reduction reaction coupled with nadh. In animal muscles when o2 supply is limited. Reduction of pyruvate to lactic acid (lactate)
