Enzymes And Digestion Flashcards
What are big molecules
Starch, proteins and fats
What are smaller molecules
Sugars, amino acids, glycerol and fatty acids
They can easily pass throw the walls of the digestive systems
What do amylase convert
Starch into sugars
What do protease convert
Proteins into amino acids
What do lipase convert
Fats into fatty acids
What does bile do
Neutralises the stomach acid and emulsified fats
Where is bile produced
In the liver
What do digestive enzymes do
Break down big molecules I to smaller ones
What does bile do
Emulsifies fats
Why does bile neutralises the acid and make conditions alkaline
Because it is an alkaline
What is causes the breakdown of food
Enzymes
What happens in the salivary glands
Produces amylase enzyme in the saliva
What happens in the liver
Where bile is produced.
What does bile do
Neutralises stomach acids and emulsifies fats
What happens in the gall bladder
Where bile is stored before it is released int the small intestine
What happens in the large intestine
Where excess water is absorbed from the food
What happens in the pancreas
Produces protease, amylase and lipase enzymes. It releases these into the small intestine
What happens in the rectum
Where the faeces are stored before passing through the anus
What happens in the stomach
Produces the protease, enzyme, pepsin
Why does the stomach produce hydrochloric acid
To kill bacteria
To give the right pH for the protease enzyme to work
