Answer the following questions 1 . What is mastication ? 2 . What food components are broken down dy Salivary amylase ? 3 . What is Emulsification ? 4 . Where the chyme is formed and what does it contain ?
Answers
Explanation:
1.
The process of chewing the food and conversion of the food to bolus is known as mastication. The process takes place in the mouth. The teeth are mainly responsible for the process of mastication. The teeth are involved in the chewing, crushing and conversion of the particles of the food. The food is grounded by the teeth by arranging the food with the cheek and the tongue. The food is mixed with saliva and then the bolus is formed. This is an important process in the digestion of food.
2. The salivary amylase breaks down amylose and amylopectin into smaller chains of glucose, called dextrins and maltose. The increased concentration of maltose in the mouth that results from the mechanical and chemical breakdown of starches in whole grains is what enhances their sweetnes.
3. emulsification (in digestion) The breakdown of fat globules in the duodenum into tiny droplets, which provides a larger surface area on which the enzyme pancreatic lipase can act to digest the fats into fatty acids and glycerol. Emulsification is assisted by the action of the bile salts.
4. Chyme is part liquid and part solid: a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and small intestine during digestion. Chyme also contains cells from the mouth and esophagus that slough off from the mechanical action of chewing and swallowing.
