Document Summary
Heart and circulation provide 02 and fuel to demand (skeletal muscle) Skeletal muscle releases fuel by-products (lactate, carb and fat cy-products), c02 and heat back to circulation. Supply tissues (liver and fat) give fuel to circulation and heart. Study of energy transfer via chemical reactions in living tissues. Energy transfer = thermodynamics (heat, chemical, mechanical, electrical) Fuel in the form of carbs, fats and proteins (dependent on type of activity) give energy for physiological functions (calcium and sr and na+/k+ pumps) 1st law: energy cannot be created of destroyed only transferred from one form to another. Total energy = usable energy (free, cross-bridge driven) 40%+non-usable energy (heat) When one phosphate is cleaved off energy is released by breaking high energy phosphate bond. Atp can be produced through fuel by-products until all that is left is c02 and h20 to breath out. We can"t store large amounts of atp, we have to regenerate it.
