  1. Gastric Emptying
  2. Heat Production
  3. 2-3 hr after eating.
  4. Glycogenesis
  5. Cellular Respiration
  1. a Average meal reaches duodenum in how many hrs?
  2. b *Byproduct of cellular respiration
    * Tissues generate more ATP produce more heat
    *Influenced by hormones (thyroxine & epinephrine)
    *Influenced by exercise & digestion
  3. c *Slows at exercise intensities >70-80% VO2 max
    *Same rate at rest/exercise intensities <70% VO2 max
    *Affected by persons fitness & the more fit, the less exercise affects it
    *Not affected by exercise duration
    *Affected differently by different types of activities.
    *Maximal rates 0f 1-1.2 L/hr with gastric volumes of 100-200 mL
  4. d 1. Chemical reactions generating ATP from nutrients.
    *Glucose: is broken down
    *ATP thru glycolysis (anerobic resp)
    *Pyruvic Acid
    *Krebs cycle(Aitric Acid cycle)
    *Electron Transport (energy released to make ATP & Hydrogen)

    2. The process in which the cell burns glucose to create ATP with the aid of oxygen. Cells have two different methods of turning food into usable fuel: aerobic respiration and anaerobic respiration.
  5. e (Anabolism/build up)Glucose to glycogen

5 Multiple Choice Questions

  1. *Nutrients absorbed from the digestive tract are used for all the body's cellular activities; Catabolism & Anabolism.

    *Glucose is the main energy source for body cells, the building blocks of fats & protein may metabolize for energy.
  2. Abdominal organs produce most of the body heat when?
  3. The least amt of energy needed to maintain life while body is at rest.
  4. Convection
  5. Hormonal System

5 True/False Questions

  1. Small Intestines absorption*Pores; carriers; pumps; pinocytosis (drinking in)
    * Not just a process of diffusion

    *Carriers are specific
    *Take energy (kCal) for digestion; Dietary induced thermagenesis


  2. Saliva Types*Watery-dissolve Food
    *Mucus-makes food stick together
    *Salivary amylase-begins starch digestion in mouth
