QUESTION
Which are noncaloric functions of fat? (a) Protects the internal organs from shock or injury (b) Helps in absorption of carotene and the fat soluble vitamins (c) Source of metabolic water (d) Serves as an insulation material?
OPTIONS
(A) (a) only
(B) (c) only
(C) (b) and (c) only
(D) All of the above
ANSWER
(D) All of the above
EXPLANATION
All of the above is the correct option because body fat has several noncaloric functions: it cushions and protects internal organs, facilitates absorption of carotene and fat-soluble vitamins by supplying dietary lipid, can serve as a source of metabolic water during oxidation, and provides thermal insulation. Therefore all four listed functions are valid, whereas each partial option omits one or more correct functions.
