(a) the sugar contents are drawn out.
(b) saliva converts starch into maltose.
(c) the taste buds are stimulated by chewing.
(d) saliva converts starch into glucose.
When a piece of bread is chewed, it tastes sweet because saliva converts starch into maltose. The salivary glands found in the mouth secrete saliva. Salivary amylase is a digesting enzyme that is present in saliva. The starch in the diet is converted to maltose by salivary amylase. Maltose is a sugar that tastes sweet. Therefore, as you chew the piece of bread, saliva transforms starch into maltose.
Saliva’s function in the Body
- It makes the mouth wet.
The oral cavity’s lining is covered by saliva, which gives the epithelial cells their hydration. Without saliva, a dry environment will form, which will harm the epithelial lining of the oral cavity.
- The blending of dietary ingredients
The tongue is used to combine saliva and food particles when you chew your food. When food particles are properly mixed, they are completely incorporated and prepared to enter the food pipe.
- Perception of flavors
Saliva is a fluid that enables the complete mixing of tiny particles and substances. Additionally, it makes sure that the chemicals get to the tongue’s taste buds, which are responsible for taste.
- Degradation of starch
Saliva contains an enzyme called salivary amylase, which breaks down starch molecules into simple carbohydrates.
Summary:
When a piece of bread is chewed, it tastes sweet because? (a) the sugar contents are drawn out (b) saliva converts starch into maltose (c) the taste buds are stimulated by chewing (d) saliva converts starch into glucose
Chewing bread imparts a sweet flavor because saliva turns starch into maltose. A watery substance called saliva is released in the oral cavity. Salivary glands are the organs that produce saliva.
