Q. Which of the following statement is/are correct
- Optical isomers have different organoleptic properties
- Threshold quantity of two optical isomers are same under constant condition
- Dill caraway have (-)ve carvone
- All of the above
Answer: a)
Optical isomers have the same physical properties: Melting point, boiling point, density etc. They have the same specific rotations but with opposite signs. Three forms of lactic acid are known, of which two are optically active and the third one is optically inactive.

- an emulsion
- a solution
- a precipitate
- None of the above

Q. The major duty of two muscle proteins filaments actin and myosin is
- to provide color to muscle
- to facilitate muscle contraction
- to bind the endomysium to the sarcolemma
- 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
- There is increase in starch content
- There is increase in glucose content
- There in increase in both glucose and starch
- 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.
