Anaerobic breakdown of glucose yields energy to muscle when energy demand surpasses the bodys ability to produce energy aerobically, but it does require large amounts of muscle glycogen reserve. What happens if glycogen is depleted, but the energy need is still high?
   
  1.Muscles use fat for energy
  2.Fatigue sets in
  3.Capacity for work decreases
  4.More oxygen is required
  5.Both fatigue sets in and capacity for work decreases are true.

Q. 2

Soluble fiber is described as viscous because it:
 a. is tough and stringy.
 b. is indigestible by human enzymes.
  c. binds to minerals in the GI tract.
 d. is soluble in fats.
 e. forms gels.

Q. 3

Studies on high-carbohydrate diets and physical endurance in runners show dietary carbs increased maximum endurance, even though fats have more than twice the energy of carbs. How could this be true?
  1.Dietary fat isnt used directly for energy.
  2.Aerobic activity relies on glucose for energy.
  3.Energy from fat metabolism is released by a slower path than carbs.
  4.Dietary fat isnt used directly for energy & aerobic activity relies on glucose for energy.
  5.Aerobic activity relies on glucose for energy & energy from fat metabolism is released by a slower path than carbohydrate.
