  4. What are the differences in the two types of starch, amylose and amylopectin?
    • Amylose is a linear polysaccharide with α-1,4 bonds
    • Amylopectin is a branched polysaccharide with α-1,6 bonds
  5. what are the three parts of a kernel of wheat and which part has the most fiber? Which part contains vitamins and minerals? Which part is mostly made of starch?
    • germ, endosperm, bran
    • bran has the most fiber
    • germ contains vitamins and minerals
    • endosperm is made mostly of starch
  6. What are maltase and α-dextrinase?
    They are enzymes located on the brush border that break up sugars into single glucose molecules.
  7. SGLT1
    location
    type
    movement
    • brush border
    • secondary active transport
    • 1 glucose and 2 Na+ into enterocyte
  8. GLUT2
    location
    type
    movement
    • basolateral membrane
    • facilitated diffusion
    • 1 glucose from enterocyte to blood
  9. GLUT5
    location
    type
    movement
    • brush border
    • facilitated diffusion
    • 1 fructose into enterocyte
  10. Na/K ATPase Pump
    location
    movement
    • basolateral membrane
    • 2 K+ into enterocyte and 3 Na+ to blood
  11. What is a by-product of lactose fermentation?
    Fermentation of lactose produces CO2 which can cause symptoms of abdominal cramping, flatulence, and diarrhea.
  12. What causes the difference in lactose content in some dairy products?
    lactobacillus in processed dairy products can break down much of the lactose
  13. Genetics of lactase persistence
    • autosomal
    • persistence is dominant over non-persistence phenotype
    • heterozygotes tend not to be lactose intolerant
