Document Summary
Chemical energy, which is converted into atp to power cellular processes. Organic building blocks, such as organic carbon and organic nitrogen, to synthesize a variety of organic molecules. Electrolysis to produce o2 (2h20 -> 2h2 + o2) *relationship of bmr per kilogram of body mass to body. Ruminants - fermentation chambers, where mutualistic microorganisms digest cellulose. Gas diffusion increases with surface area and decreases with distance. Respiratory surfaces are built to maximize the surface area and have the blood as close to the air/water as possible. Further away the source, the harder it is to pull. If the partial pressure of gas in water is greater than the atmosphere, it will boil out. Key *: use countercurrents between the gills and the water to such the air out of the water. This is because air moves from high to low pressure. A single hemoglobin can carry four o2 molecules. One molecule for each iron containing heme group.
