Enzymes And Digestion Flashcards
(26 cards)
What are enzymes used in digestion produced by, and where are they released?
They are produced by cells and then released in the gut to mix with food
What type of molecules do digestive enzymes break down?
Big ones
Give 3 examples of big molecules
Starch, proteins, and fats
Why do big molecules get broken down?
They are too big to pass through the walls of the digestive system, so by breaking them down, the soluble can pass through easily and be absorbed into the bloodstream
What do proteins get broken down into?
Amino acids
What does starch get broken down into?
Glucose
What do fats get broken down into
Fatty acids and glycerol
What do carbohydrases convert?
Carbohydrases convert carbohydrates into simple sugars
Give an example of a carbohydrase.
amylase
What breaks down starch?
Amylase
What are the three places amylase is made in the body?
The salivary glands, the pancreas, and the small intestine
What does protease convert?
Protease converts proteins into amino acids
What 3 places in the body is protease made?
The stomach (called pepsin), The pancreas, and the small intestine
What do lipases convert?
Lipases convert lipids into glycerol and fatty acids
Which 2 places are lipases made?
The pancreas and the small intestine.
What does the body do with the products of digestion?
They can be used to make new carbohydrates, proteins, and lipids.
What does bile do to stomach acid?
Neutralises it
What does bile do to fats?
Emulsifies it
Where is bile produced?
In the liver
Where is bile stored?
The gall bladder
Where is bile released?
The small intestine.
What makes the pH too acidic for enzymes in the small intestine?
Hydrochloric acid
Is bile an acid or alkaline?
