HideShow resource information
What are starch, proteins and fats?
They are big molecules which are too big to pass through the walls of the digestive system
1 of 7
What are sugars, amino acids, glycerol and fatty acids?
They are small molecules that pass easily through the walls of the digestive system.
2 of 7
What do digestive enzymes do?
They break down the big molecules into smaller ones.
3 of 7
What are the three digestive enzymes?
carbohydrases, proteases and lipase
4 of 7
What do carbohydrases do? e.g. (amylase)
Carbohydrases digest starch into sugars
5 of 7
What do proteases do? (e.g. pepsin)
They digest proteins to amino acids.
