5 Matching Questions

  1. Basal Metabolism
  2. Digestion in Small Stomach/ Small Intestine
  3. Metabolism
  4. Glucose
  5. Stomach Digestion
  1. a Broken down(Catabolism), known as glycolysis, occurs in the Cytoplasm in the Anaerobic. Produces +2 ATP molecules.
  2. b The least amt of energy needed to maintain life while body is at rest.
  3. c *duodenum
    *jejunum
    *ileum
  4. d *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.
  5. e 1. Semi-liquid & contains ~50% water

    2. Process:
    *Food remain in stomach about 0.5-2hr
    *Gastric juice (mucus, HCL)=2000-2500 mL/d

    3. Food Leaves:
    *CHO:protein;lipid(takes the longest)

    4. Stomach emptied in 1-4 hr
    *Strenuous Exercise may delay gastric emptying by decreased blood flow
    *Lipid & protein delay gastric emptying

5 Multiple Choice Questions

  1. Amino Acids (Essential & Non-Essential)
  2. Hard, dry, infrequent stools
    Reduced by high fiber, fluid intake, exercise
  3. 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.
  4. Amino acids to proteins, glucose to starch
  5. *Surface of Skin
    *Second, thru expiration of air
    *Elimination of urine & Feces

5 True/False Questions

  1. Glycogenolysis(Catabolism/break down)Glycogen to glucose

          

  2. Absorptive Mechanisms*Passive diffusion
    *Facilitated diffusion
    *Active transport

          

  3. Glucose MetabolismCarb-> Glycogen->glucose ->glycogen

          

  4. Gastric Emptying*High CHO, osmolality, protein/amino acids & low pH

          

  5. ChymeWell liquefied mass in stomach ->(pylorus)
