The whole digestion process starts even before the food reaches our mouth as hunger and appetite are two major components of the cephalic phase of digestion‚ which is the stimulation and release of digestive juices in preparation of the food. Once inside the mouth‚ my teeth and salivary enzymes help to break down the food components into smaller molecules. This chemical amylase in our mouth helps to start breaking down the food chemically in

    Concentarion ENZYME LAB Introduction- Enzymes are proteins that speed up the rate of reactions in living things. In this lab‚ we will perform four experiments exploring the way enzymes work. PART A: pH SPECIFICITY Every enzyme has a specific pH at which it works best. In this section‚ you will determine which pH is best for the enzyme‚ catalase. Living tissues produce the enzyme catalase‚ which is able to break down hydrogen peroxide into oxygen gas and water. The reaction is

    beginning to end. Where does the food go? As food enters the mouth‚ both mechanical and chemical digestion begins. First the food is physically broken down by the mechanical process of mastication (chewing)‚ into smaller particles‚ creating a bolus with the tongue against the soft plate. During this phase‚ the salivary glands mix the food with salivary amylase beginning the chemical digestion of starches. The bolus then enters the pharynx (throat) first then is routed to the esophagus. These
