B2 - Enzymes and Digestion

  • Breaking down molecules
  • Conversions
  • Stomach processes
HideShow resource information
What types of molecules can pass through the stomach and what can't?
Starch, proteins and fats are too big and need to be broken down. Sugars, amino caids, glycerol and fatty acids are small molecules and don't need to be broken down.

What is starch converted into?
Amylyse converts starch to sugar (maltose). It is found in the salivary glands, the pancreas and the small intestine.
2 of 6
What are proteins converted to?
Protease converts proteins into amino acids. It's found in the stomach, the pancreas and the small intestine.
3 of 6
What are lipids converted to?
Lipase converts lipids into glycerol and fatty acids. It's found in the pancreas and small intestine.

How does bile help enzymes?
The HCL in the stomach is too acidic for enzymes in the small intestine. Bile is alkaline so makes the solution alkaline for the enzymes.
5 of 6
How does bile emulsify fats?
It breaks the fat into tiny droplets. This gives it a larger surface area of fat for the enzyme lypase to work on, which makes digestion faster.
