Enzymes and Digestion Flashcards
What are 3 examples go big molecules?
Starch, protein and fats
What do digestive enzymes do?
Break down the big molecules into smaller molecules
What are 4 examples of small molecules?
Fatty acids
Amino acids
Glycerol
Sugars
What does amylase do?
Converts starch into sugars (eg.maltose
Where is amylase made?
The salivary glands
The pancreas
The small intestine
What does protease do?
Converts proteins into amino acids
Where is protease made?
The stomach (where it's called pepsin) The pancreas The small intestine
What does lipase do?
Converts lipids into glycerol and fatty acids
Where is lipase made?
The pancreas
The small intestine
Where is bile produced?
The liver
Where’s bile stored?
The gall bladder
Where is bile released into?
The small intestine
What is bile used for in the stomach?
The hydrochloric acid in the stomach makes the PH too acidic for enzymes in the small intestine to work properly. Bile is an alkaline and so it neutralises the acid and and makes conditions alkaline. The enzymes in the small intestine work better in these alkaline conditions.
Other than neutralising stomach acids, what is bile used for?
Bile emulsifies fats. It breaks down the fat into tiny droplets which gives a bigger surface area of fat for the enzyme lipase to work on which makes it’s digestion faster.
