Digestion is the chemical breakdown of food molecules into smaller molecules that can be used by various cells within the body. The breakdown is initiated when food is ingested in the mouth and specific enzymes are exposed to components within the food molecules. Digestion begins in the mouth with mastication

them to build and nourish cells; and to provide energy. Food travels though the digestive tract by muscle contraction called peristalsis. This journey of digestion can take up to twenty four hours. Digestion begins in the mouth where the teeth break food down into smaller particles during mastication. Salivary glands secrete saliva which begins chemical digestion and keeps the food moist. Swallowed food is pushed into the pharynx by the contraction of multiple muscle of the face‚ neck and tongue

Amylase’s Ability to Breakdown Starch. Abstract This experiment was designed to test the reaction of the enzyme amylase at various temperatures. There were two different kinds of amylase being tested‚ one was fungal amylase also known as aspergillus oryzae and human amylase. The changes in temperature effect the rate at which an enzyme and a substrate collide. When the temperature is too high the active site changes shape or denatures‚ once this occurs it stops substrates from attaching themselves

Digestion is the complex process of turning the food you eat into the energy you need to survive. The digestion process also involves creating waste to be eliminated. The digestive tract (or gut) is a long twisting tube that starts at the mouth and ends at the anus. It is made up of a series of by muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food. Along the way are three other organs that are needed for digestion: the liver

Babysitting an Infant If you’re babysitting a child in his or her first year of life and who hasn’t learned to walk yet‚ it’s not the same as taking care of a toddler or an older child. Infants are very fragile and require special attention and care. Step 1: Have a fill in form ready for the parents. It should include parent emergency contact info‚ what to feed the baby‚ the baby’s allergies‚ and other stuff you should know in case of an emergency. Step2: Make sure the baby is comfortable

DIGESTION OF CARBOHYDRATES Digestion of carbohydrate begins in the mouth‚ with the secretion of the enzyme salivary amylase from the serous cells of the salivary gland. This enzyme breaks starch and glycogen into disaccharides. The mucous cells of the salivary gland secrete a mucus‚ which causes the food to stick together‚ and acts as a lubricant to aid in swallowing. The salivary glands are grouped into three categories: the parotid gland‚ submandibular glands‚ and sublingual‚ all located
