 Food is covered into its simplest form so that it can
dissolve and diffuse through the wall of the small
intestine. Its then enters the blood to be transported
to all parts of body
End product of carbohydrate ,
protein and fat digestion
STARCH
SMALLER, SOLUBLE
MOLECULES
LARGE ,INSOLUBLE
MOLECULES
PROTEIN
GLUCOSE
AMINO ACIDS

4. FAT GLYCEROL AND FATTY ACIDS
The digestion of different types of food occurs in
different parts of the digestive tract
This is because different enzymes are secreted in
different parts of digestive tract
Each type of enzyme breaks down a specific food
substance (substrate)
The end products are now ready for absorption

5. Why does rice ,which has been chewed for
a while in a mouth , taste sweet ?
An enzyme in the saliva has changed the
rice (a carbohydrate) into a simple
sugar called maltose
