(i)Food components         (a ) Product of digestion

(ii) Carbohydrates              (b) fatty acid glycerol

(iii)Lysine                           (c) sugar

(iv)Lipase                             (d)amino acid

Solution

• 1. Products of digestion are the components in food such as carbohydrates, fatty acids & glycerol. 
• 2. Carbohydrates, or carbs, are sugar molecules. Along with protein & fats, carbohydrates are one of the three main nutrients found in food & drinks. 
• 3. Lysine is an α-amino acid that is a precursor to many proteins. It contains an α-amino group, an α-carboxylic acid group, and a side chain lysyl, classifying it as a basic, charged, aliphatic amino acid. It is encoded by the codons AAA and AAG. 
• 4. Methionine aids in the breakdown of fat by preventing its accumulation in the arteries and its conversation into fatty acids & glycerol is made possible with the help of lipase enzyme.
