bio182 homeostasis

NAU study guide

QuestionAnswer
Homeostasis The ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes.
Negative feedback any change or deviation from the normal range of function is opposed, or resisted.(reverse cooling trend)
Acclimization is the process of an organism adjusting to chronic change in its environment, often involving temperature, moisture, food, often relating to seasonal climate changes.
Endotherms Body temps determined by internal sources. Heat produced metabolically. (humans)
ectotherms Body temps determined by external heat sources (lizard)
heterotherms Mix of both. Hibernation- summer is endothermic. Winter is ectothermic.
Endotherms regulate temp by sweating, water. Radiation- infrared (sun, fire) Conduction(direct contact). Convection (air/water/wind)
How do iguanas control temp while feeding? They lose their heat. When they get too cold, they'll bask on a hot rock.
How do bees regulate temp? temp regulation by group. brood remains at 34
Shivering Skeletal muscles use ATP to relase energy in form of heat.
Brown fat Protons leak across mitochondrial membrane. Metabolic fuels used w/o ATP production.
Adaptation differences for organisms in artic vs desert environments Desert- long ears for heat exchange. Artic- thick fur, smaller legs and ears.
hypothermia- Below normal body temperature. Humming birds drop temp during inactive periods which increases their time they can survive w/o food.
Regulated hyptothermia Hibernation
