BIOL 1002 Chapter : Ch 31 Homeostasis Part 1
Document Summary
Chapter 31: homeostasis & the organization of the animal body. The body actively adjusts to ongoing internal and external changes to maintain constant conditions dynamic constancy. Why are cells so picky: animals cells produce and use lots of atp. To produce atp, continuous supplies of high-energy molecules (primarily glucose) and o2 are required. So, energy production is why glucose and oxygen levels are important: also, proteins" structures are maintained by hydrogen bonds, which can be disrupted if the. Each of the reactions for producing atp is catalyzed by a protein environment is too hot, salty, acidic, or basic: maintaining these bonds helps explain the requirement for a narrow range of temperature, ph, and salt. Animals groups are not all alike in their homeostatic abilities: birds and mammals are highly efficient at maintaining homeostasis, other animals have reduced or absent homeostasis for one or more aspects of their internal environment.
