The digestive system

Chapter 4

Digestion is the breakdown of food
Physical digestion involves using the teeth and churning in the stomach
Chemical digestion involves using enzymes
this enzyme breaks down starch into maltose amylase
Enzymes are similar to catalysts
a catalyst speeds up a chemical reaction but it is not used up and can be reused
teeth used for cutting food are called incisors
teeth used for tearing food are called canine
Teeth used for chewing and grinding are called molars and premolars
Acid found in the stomach Hydrochloric
food is absorbed into the bloodstream in the small intestine
the liver makes bile
the pancreas makes insulin and enzymes
insulin controls levels of sugar in the blood
diabetes occurs if you do not have enough insulin
in an experiment using the enzyme amylase what is the substrate starch
in an experiment using amylase and starch what is the product maltose
