Document Summary
Classical elements updated: earth, water, air, and fire. Element in their pure form can be incredibly dangerous and destructive. ~10% water protein carbs nucleic acids lipids, fats small organic molecules. So many people think it"s burned, but they don"t, in fact, look at the big picture and see that if you actually burned fats, we would pretty much explode. Instead, humans adopt gentle energy: oxidations and other biological reactions require elaborate mechanisms to produce gentle amounts of energy. You can"t just use fire or convert mass to energy: we break chemical bonds to get energy. Atp: like a checking account, the working currency. Phosphocreatine: like a savings account, the back up. How fat leaves the body: 84% of triglyceride"s mass is exhaled as co2, 16% of triglyceride"s mass is excreted as h2o. Via urine, tears, breath, swear, other bodily fluids: amount you can breathe out is rate limiting. Lose about 203g of carbon as co2 per day.
