                  The part ‘a’ of this question was  answered correctly while other parts ‘b;’ and ‘c’ were not well tackled by the  majority of the candidates. 
                    The candidates were  expected to answer the question as follows: 
                     (a)     FUNCTIONS  OF FATS IN THE BODY 
                      (i)      They  are good sources of energy. 
                      (ii)      They  spare protein. 
                      (iii)     They  assist in the maintenance of constant body temperature. 
                      (iv)     They  cushion the delicate organs in the body. 
                      (v)      They facilitate the absorption of the  fat-soluble vitamins. 
                      (vi)     They contribute to flavour and palatability  of the diet. 
                      (vii)    They provide satiety and delay the onset of  hunger. 
                      (viii)   They promote healthy hair and skin. 
                      (ix)     They provide essential fatly acids needed  for good health. 
                     (x)      They provide the body with fat soluble vitamins. 
                      (xi)     They form part of the cell membranes  throughout the body        especially in  the brain. 
                                                                                
   (b)    REASONS WHY SOME AMINO ACIDS ARE ESSENTIAL 
                      (i)      The body cannot produce them, hence must  be supplied  
                                by the food eaten. 
                      (ii)      They  are indispensable. 
                      (iii)     They  are also complete protein. 
                      (iv)     They  are mostly obtained from animal sources. 
                                                                                
                      (c)      EXAMPLES OF ESSENTIAL AMINO ACIDS 
                      Isolencine, leucine, valine,  threonine, lysine, tryptophan, phenylalanine, methionine, histidine and arginine for the children.
