5 Matching questions

  1. Convection
  2. Heat Production
  3. Peripheral (Proteins)
  4. Receptor
  5. Carbohydrates (Cell Membrane)
  1. a Transfer of heat from the body by currents (air and water).
  2. b * Found absorbed or attached on the outside surface(s) of the bilayer
    * Cell-surface antigens and hormone receptors
  3. c Catabolic reactions generate the most.
  4. d These cells are found only on outer half of the lipid bilayer as a thin sugar coating, called the cell coat or glycocalyx. Cell communication: receptors for binding hormones, cell adhesion (cohesive tissue), immune reaction.
  5. e Monitors changes in a controlled condition, a desired value or set point, by sensors through an afferent pathway.

5 Multiple choice questions

  1. Fluid found within the cells.
  2. Epinephrine, nor epinephrine, and thyroxin cause uncoupling to occur reducing the number of ATP's produced in the electron transport in the aerobic pathway. Fewer ATP's results in greater heat (26 less ATP * 7.3 kcal / ATP = 189.9 kcal of heat). Infants can double heat production; adults can have a 10-15% increase.
  3. Condition due to cold weather or icy water. Core temperature < 91 °F. Leads to sleep, coma, and death.
  4. Built the first compound microscope; coined "cell"; used microscope to study how insect feed adhered to wet slippery surfaces.
  5. BIG Idea "The internal conditions of the body remain fairly stable even when external conditions are highly variable. The body is never at rest, but is constantly undergoing dynamic changes." Purpose of these changes was to maintain an internal equilibrium; physiology became a separate science.

5 True/False questions

  1. High Extracellular Ion ConcentrationsNa⁺, Ca²⁺, Cl⁻, HCO₃

          

  2. Survivable Ambient Temperature RangeExposure to cold temperatures down to 55 °F or hot temperatures up to 130 °F. (Subject nude in dry air.)

          

  3. Anatomic Subdivisions of Nervous SystemSensory Input; Integrative; Motor Output/Response

          

  4. Ibn Sina (980-1037)* These proteins span the entire lipid bilayer
    * May act as ion channels and transporters (e.g. Na⁺, K⁺, Ca²⁺, and Cl⁻) across the membrane
    * Act as receptors for neurotransmitter substances, receptors for nerve growth, and adhesion factors

          

  5. Chemical Thermogenesis* Isolates the cell
    * Regulates the intracellular and extracellular ionic environment
    * Comprised of a phospholipid bilayer
