The digestion process The digestion process begins in the mouth. First we take a bite of food. The presccence of food in the mouth stimulates the flow of saliva from the salivary glands. Saliva moistens the food and carries dissolved food molecules to the taste buds. Saliva helps digest food because it contains enzymes that start to break it down. After the food is covered with saliva‚ you then begin to chew your food. Chewing breaks down food into smaller pieces and also breaks apart fiber that

Define the following terms: Digestion: Digestion is the breakdown of large insoluble food substances in small and soluble one by means of mechanical and chemical actions. Peristalsis: It is a series of alternate contraction and relaxation of the circular and longitudinal muscles‚ producing a wave-like motion to move food down the oesophagus‚ from the mouth to the stomach. Emulsification: It is the hydrolysis of a few large fat globules into many small and soluble fat molecules. Transpiration:

Cynthia Vang Derrick 24 Title: Digestion of Starch Problem: Hypothesis: If synthetic saliva breaks down the cracker the most Then more of the cracker should be digested Because synthetic saliva contains amylase‚ and amylase helps break down complex carbohydrates.

Living Digestion The first step in the journey of a sandwich is the mouth‚ where mastication occurs. The salivary glands secrete saliva which includes enzyme amylase. The teeth masticate and reduce the food into smaller pieces. The tongue moves the food around and enables swallowing. While the food is being broken into smaller pieces‚ amylase breaks down the carbohydrates found in the bread. After chewing (or mastication) is done‚ the food moves down the esophagus through peristalsis. The epiglottis

Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for
