Document Summary
Things animals do that we will try to observe in protists. When cell is small, the volume has a lot of surface area to do stuff. Actual surface area is about the size of a football field. In small things, metabolic waste is able to diffuse out. Nitrogenous waste *** metabolic waste is only nitrogen*** Need to take nitrogen out of carbon, come off as ammonia. Can diffuse into mitochondria and shut down the function even at tiny amount. Only organisms living in a marine environment because the ammonia can diffuse out when made. Ammonia made into this with even more atp. Uric acid ring to make nucleotide, can hide toxic n in that and just stop the process. Uric acid is non toxic and can be built up, used by all insects. **** metabolic waste, not fecal waste**** on exam. Phagocytosis gaining nutrients in water but are particulate.
