Biology Form Four Digestion Digestion is the process by which food is broken down from complex insoluble substances into simple soluble substances. There are two types of digestion – chemical digestion and mechanical digestion. Mechanical digestion involves breaking up large pieces of food into smaller pieces. This provides a large surface area for the action of enzymes on food. There is no change to the chemical composition of food during mechanical digestion. Mechanical digestion occurs in the...

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...

metabolized in the body! 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, or chewing, performed by the teeth. The purpose of chewing is to grant the food more exposure to enzymes, therefore allowing chemical digestion to occur faster. The presence...

Digestion of Starch by Salivary Amylase

The role of salivary amylase in the digestion of starches remains controversial. In the absence of pancreatic amylase, the key enzyme for starch digestion, salivary amylase may well represent a potential compensatory alternate pathway for the digestion of amylose, amylopectin, and glycogen. Clinically significant depression of pancreatic amylase occurs in chronic pancreatitis, pancreatic resection, pancreatic neoplasm, cystic fibrosis, and other causes of pancreatic insufficiency.
