| Q.7 | Sentences of a paragraph are given below in jumbled order. Arrange the sentences in the correct order to form a meaningful and coherent paragraph. P) Many carnivores, such as dogs and cats, have no amylase in their saliva; therefore, their natural diet contains very little starch. Q) Saliva dissolves some of the chewed food and acts as a lubricant, facilitating passage through the subsequent portions of the digestive tract. R) Saliva also contains a starch-digesting enzyme called amylase (ptyalin), which initiates the process of enzymatic hydrolysis; it splits starch (a polysaccharide containing many sugar molecules bound in a continuous chain) into molecules of the double sugar maltose. S) Substances must be in solution for the taste buds to be stimulated; saliva provides the solvent for food materials. | |
