Relevant chapter: B3 Organisation and the digestive system. AQA Biology third edition textbook-Page 46-47
Students are required to know the following;
Students should be able to recall the sites of production and the action
of amylase, proteases and lipases.
Students should be able to understand simple word equations but no
chemical symbol equations are required.
Digestive enzymes convert food into small soluble molecules that can be
absorbed into the bloodstream.
Carbohydrases break down carbohydrates to simple sugars. Amylase is
a carbohydrase which breaks down starch.
Proteases break down proteins to amino acids.
Lipases break down lipids (fats) to glycerol and fatty acids.
The products of digestion are used to build new carbohydrates, lipids
and proteins. Some glucose is used in respiration.
