Document Summary
Obj 1 define homeostasis, explain its importance and specify three conditions that must be fulfilled. The human body has an internal environment, distinct from its external environment. Maintenance of the internal environment is conceptualized as homeostasis. Homeostasis the condition in which body"s internal environment remains relatively constant, within limits. Chemicals/enzymes involved in complex chemical reactions operate within a narrow range of conditions. Constancy of reactions is important for allowing chemical reactions to take place at the necessary rates. If conditions weren"t constant reactions would occur slowly or not at all causing illness/death. One there must be a proper concentration of gases, nutrients, water and salts. Oxygen cellular respiration that produces energy. Carbon dioxide waste product of cellular respiration but also used for other processes. Nutrients raw materials for chemical reactions. Water and salts fluid and electrolyte balance of the body (determines its chemistry) Shapes of many enzymes are temperature dependent if they overheat they break down.
