Q. The major duty of two muscle proteins filaments actin and myosin is

  1. to provide color to muscle
  2. to facilitate muscle contraction
  3. to bind the endomysium to the sarcolemma
  4. None of the above

Answer: b)

Muscle contraction thus results from an interaction between the actin and myosin filaments that generates their movement relative to one another. The molecular basis for this interaction is the binding of myosin to actin filaments, allowing myosin to function as a motor that drives filament sliding. The type of myosin present in muscle (myosin II) is a very large protein (about 500 kd) consisting of two identical heavy chains (about 200 kd each) and two pairs of light chains (about 20 kd each).

Q. If potato is stored at more than 10C

  1. There is increase in starch content
  2. There is increase in glucose content
  3. There in increase in both glucose and starch
  4. No change in either glucose or starch

Answer: a)

Potatoes stored below 5° Celsius do not sprout. Potatoes stored above 5° Celsius do sprout. The higher the storage temperature, the more chance of germination, which creates serious problems resulting in significant losses.
